Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631662, here are decompositions:

3 + 8631659 = 8631662
163 + 8631499 = 8631662
211 + 8631451 = 8631662
271 + 8631391 = 8631662
283 + 8631379 = 8631662
331 + 8631331 = 8631662
379 + 8631283 = 8631662
433 + 8631229 = 8631662

Showing the first eight; more decompositions exist.
