Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630518, here are decompositions:

41 + 8630477 = 8630518
101 + 8630417 = 8630518
131 + 8630387 = 8630518
227 + 8630291 = 8630518
269 + 8630249 = 8630518
311 + 8630207 = 8630518
317 + 8630201 = 8630518
359 + 8630159 = 8630518

Showing the first eight; more decompositions exist.
