%N Perfect squares which are not the sum of two primes.
%F A106544 with 0's removed.
%e a(2)=121 because it is the second perfect square which is impossible to obtain summing two primes.
%e 100 is not in the sequence because 100=97+3 (sum of two primes).
%Y Cf. A106544-A106548, A106563-A106564, A106571, A106573-A106575, A106577.
