%N Primes of the form x^2 + xy + 17y^2, with x and y nonnegative.
%C Discriminant = -67.
%C Different from A191041: 151 decomposes in Q(sqrt(-67)) since 151 = ((1 + 3*sqrt(-67))/2) * ((1 - 3*sqrt(-67))/2); nevertheless, x^2 + xy + 17y^2 = 151 has no nonnegative solution. - _Jianing Song_, Feb 19 2021
