Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631812, here are decompositions:

31 + 8631781 = 8631812
43 + 8631769 = 8631812
139 + 8631673 = 8631812
313 + 8631499 = 8631812
421 + 8631391 = 8631812
433 + 8631379 = 8631812
439 + 8631373 = 8631812
613 + 8631199 = 8631812

Showing the first eight; more decompositions exist.
