Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631426, here are decompositions:

47 + 8631379 = 8631426
53 + 8631373 = 8631426
59 + 8631367 = 8631426
107 + 8631319 = 8631426
149 + 8631277 = 8631426
157 + 8631269 = 8631426
179 + 8631247 = 8631426
197 + 8631229 = 8631426

Showing the first eight; more decompositions exist.
