Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631646, here are decompositions:

17 + 8631629 = 8631646
29 + 8631617 = 8631646
47 + 8631599 = 8631646
113 + 8631533 = 8631646
167 + 8631479 = 8631646
479 + 8631167 = 8631646
563 + 8631083 = 8631646
743 + 8630903 = 8631646

Showing the first eight; more decompositions exist.
