Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631528, here are decompositions:

11 + 8631517 = 8631528
29 + 8631499 = 8631528
127 + 8631401 = 8631528
137 + 8631391 = 8631528
149 + 8631379 = 8631528
197 + 8631331 = 8631528
251 + 8631277 = 8631528
277 + 8631251 = 8631528

Showing the first eight; more decompositions exist.
