Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631396, here are decompositions:

5 + 8631391 = 8631396
17 + 8631379 = 8631396
23 + 8631373 = 8631396
29 + 8631367 = 8631396
89 + 8631307 = 8631396
113 + 8631283 = 8631396
127 + 8631269 = 8631396
149 + 8631247 = 8631396

Showing the first eight; more decompositions exist.
