Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631956, here are decompositions:

13 + 8631943 = 8631956
283 + 8631673 = 8631956
439 + 8631517 = 8631956
457 + 8631499 = 8631956
577 + 8631379 = 8631956
673 + 8631283 = 8631956
709 + 8631247 = 8631956
727 + 8631229 = 8631956

Showing the first eight; more decompositions exist.
