%N A064233 Numbers which are not the sum of a prime number and a nonzero square.
%C A064233 The sequence is infinite, cf. A014090. Subsequence of squares = A053726^2. 
               Subsequence of nonsquares is disjoint union of A020495 and A065377 
               and so is probably finite. - Vladeta Jovovic (vladeta(AT)eunet.rs),
