Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631776, here are decompositions:

7 + 8631769 = 8631776
103 + 8631673 = 8631776
277 + 8631499 = 8631776
397 + 8631379 = 8631776
409 + 8631367 = 8631776
457 + 8631319 = 8631776
499 + 8631277 = 8631776
547 + 8631229 = 8631776

Showing the first eight; more decompositions exist.
