Pairs of numbers (a,b) such that a + b*I is a first-quadrant Gaussian prime, ordered by a+b and then a.

1, 1, 0, 3, 1, 2, 2, 1, 3, 0, 1, 4, 2, 3, 3, 2, 4, 1, 0, 7, 1, 6, 2, 5, 5, 2, 6, 1, 7, 0, 2, 7, 4, 5, 5, 4, 7, 2, 0, 11, 1, 10, 3, 8, 5, 6, 6, 5, 8, 3, 10, 1, 11, 0, 3, 10, 4, 9, 5, 8, 8, 5, 9, 4, 10, 3, 1, 14, 2, 13, 4, 11, 7, 8, 8, 7, 11, 4, 13, 2, 14, 1

1,4

Gaussian primes on the positive real and imaginary axes are included. Note that the primes are ordered by their taxicab distance from the origin.

nn = 20; t = {}; Do[If[PrimeQ[i + (j - i) I, GaussianIntegers -> True], AppendTo[t, {i, j-i}]], {j, 0, nn}, {i, 0, j}]; Flatten[t]
