Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631590, here are decompositions:

73 + 8631517 = 8631590
139 + 8631451 = 8631590
199 + 8631391 = 8631590
211 + 8631379 = 8631590
223 + 8631367 = 8631590
271 + 8631319 = 8631590
283 + 8631307 = 8631590
307 + 8631283 = 8631590

Showing the first eight; more decompositions exist.
