Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631386, here are decompositions:

7 + 8631379 = 8631386
13 + 8631373 = 8631386
19 + 8631367 = 8631386
67 + 8631319 = 8631386
79 + 8631307 = 8631386
103 + 8631283 = 8631386
109 + 8631277 = 8631386
139 + 8631247 = 8631386

Showing the first eight; more decompositions exist.
