Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631492, here are decompositions:

13 + 8631479 = 8631492
41 + 8631451 = 8631492
101 + 8631391 = 8631492
113 + 8631379 = 8631492
151 + 8631341 = 8631492
173 + 8631319 = 8631492
223 + 8631269 = 8631492
241 + 8631251 = 8631492

Showing the first eight; more decompositions exist.
