Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530490, here are decompositions:

43 + 530447 = 530490
47 + 530443 = 530490
61 + 530429 = 530490
89 + 530401 = 530490
97 + 530393 = 530490
101 + 530389 = 530490
131 + 530359 = 530490
137 + 530353 = 530490

Showing the first eight; more decompositions exist.
