Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512628, here are decompositions:

7 + 512621 = 512628
19 + 512609 = 512628
31 + 512597 = 512628
37 + 512591 = 512628
47 + 512581 = 512628
59 + 512569 = 512628
97 + 512531 = 512628
107 + 512521 = 512628

Showing the first eight; more decompositions exist.
