Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631656, here are decompositions:

139 + 8631517 = 8631656
157 + 8631499 = 8631656
277 + 8631379 = 8631656
283 + 8631373 = 8631656
337 + 8631319 = 8631656
349 + 8631307 = 8631656
373 + 8631283 = 8631656
379 + 8631277 = 8631656

Showing the first eight; more decompositions exist.
