Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631782, here are decompositions:

13 + 8631769 = 8631782
109 + 8631673 = 8631782
283 + 8631499 = 8631782
331 + 8631451 = 8631782
409 + 8631373 = 8631782
463 + 8631319 = 8631782
499 + 8631283 = 8631782
631 + 8631151 = 8631782

Showing the first eight; more decompositions exist.
