Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631468, here are decompositions:

17 + 8631451 = 8631468
67 + 8631401 = 8631468
89 + 8631379 = 8631468
101 + 8631367 = 8631468
127 + 8631341 = 8631468
137 + 8631331 = 8631468
149 + 8631319 = 8631468
191 + 8631277 = 8631468

Showing the first eight; more decompositions exist.
