Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631402, here are decompositions:

11 + 8631391 = 8631402
23 + 8631379 = 8631402
29 + 8631373 = 8631402
61 + 8631341 = 8631402
71 + 8631331 = 8631402
83 + 8631319 = 8631402
151 + 8631251 = 8631402
173 + 8631229 = 8631402

Showing the first eight; more decompositions exist.
