EXAMPLE

a(1) = 47: y = x^2+11x+47.

If x = 0; y = 0+0+47 = 47, which is prime.

If x = 1; y = 1+11+47 = 59, which is prime.

If x = 2; y = 4+22+47 = 73, which is prime.

If x = 3; y = 9+33+47 = 89, which is prime.

If x = 4; y = 16+44+47 = 107, which is prime.

If x = 5; y = 25+55+47 = 127, which is prime.

If x = 6; y = 36+66+47 = 149, which is prime.
