Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631678, here are decompositions:

5 + 8631673 = 8631678
19 + 8631659 = 8631678
61 + 8631617 = 8631678
67 + 8631611 = 8631678
79 + 8631599 = 8631678
109 + 8631569 = 8631678
179 + 8631499 = 8631678
199 + 8631479 = 8631678

Showing the first eight; more decompositions exist.
