Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530550, here are decompositions:

11 + 530539 = 530550
17 + 530533 = 530550
19 + 530531 = 530550
23 + 530527 = 530550
37 + 530513 = 530550
43 + 530507 = 530550
103 + 530447 = 530550
107 + 530443 = 530550

Showing the first eight; more decompositions exist.
