Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515628, here are decompositions:

7 + 515621 = 515628
17 + 515611 = 515628
31 + 515597 = 515628
41 + 515587 = 515628
89 + 515539 = 515628
109 + 515519 = 515628
151 + 515477 = 515628
199 + 515429 = 515628

Showing the first eight; more decompositions exist.
