Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631758, here are decompositions:

241 + 8631517 = 8631758
307 + 8631451 = 8631758
367 + 8631391 = 8631758
379 + 8631379 = 8631758
439 + 8631319 = 8631758
607 + 8631151 = 8631758
661 + 8631097 = 8631758
757 + 8631001 = 8631758

Showing the first eight; more decompositions exist.
