Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631998, here are decompositions:

19 + 8631979 = 8631998
211 + 8631787 = 8631998
229 + 8631769 = 8631998
499 + 8631499 = 8631998
547 + 8631451 = 8631998
607 + 8631391 = 8631998
619 + 8631379 = 8631998
631 + 8631367 = 8631998

Showing the first eight; more decompositions exist.
