Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631408, here are decompositions:

7 + 8631401 = 8631408
17 + 8631391 = 8631408
29 + 8631379 = 8631408
41 + 8631367 = 8631408
67 + 8631341 = 8631408
89 + 8631319 = 8631408
101 + 8631307 = 8631408
131 + 8631277 = 8631408

Showing the first eight; more decompositions exist.
