Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631608, here are decompositions:

109 + 8631499 = 8631608
157 + 8631451 = 8631608
229 + 8631379 = 8631608
241 + 8631367 = 8631608
277 + 8631331 = 8631608
331 + 8631277 = 8631608
379 + 8631229 = 8631608
409 + 8631199 = 8631608

Showing the first eight; more decompositions exist.
