Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631992, here are decompositions:

13 + 8631979 = 8631992
211 + 8631781 = 8631992
223 + 8631769 = 8631992
541 + 8631451 = 8631992
601 + 8631391 = 8631992
613 + 8631379 = 8631992
619 + 8631373 = 8631992
661 + 8631331 = 8631992

Showing the first eight; more decompositions exist.
