Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530518, here are decompositions:

5 + 530513 = 530518
11 + 530507 = 530518
17 + 530501 = 530518
71 + 530447 = 530518
89 + 530429 = 530518
179 + 530339 = 530518
239 + 530279 = 530518
251 + 530267 = 530518

Showing the first eight; more decompositions exist.
