Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630728, here are decompositions:

59 + 8630669 = 8630728
89 + 8630639 = 8630728
137 + 8630591 = 8630728
251 + 8630477 = 8630728
311 + 8630417 = 8630728
479 + 8630249 = 8630728
521 + 8630207 = 8630728
569 + 8630159 = 8630728

Showing the first eight; more decompositions exist.
