Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631738, here are decompositions:

79 + 8631659 = 8631738
109 + 8631629 = 8631738
127 + 8631611 = 8631738
139 + 8631599 = 8631738
239 + 8631499 = 8631738
337 + 8631401 = 8631738
347 + 8631391 = 8631738
359 + 8631379 = 8631738

Showing the first eight; more decompositions exist.
