%N A128292 Primes not in A126769.
%C A128292 Primes p that are not of the form k^4+s where k > 1 and s >= 1, such 
               that k^2+s is prime and smaller than p.
%e A128292 37 is prime, 2^4+21 is the only way to write 37 as k^4+s, but neither 
               2^2+21 = 25 nor 3^2+21 = 30 is prime, hence 37 is a term.
