Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631718, here are decompositions:

5 + 8631713 = 8631718
59 + 8631659 = 8631718
89 + 8631629 = 8631718
101 + 8631617 = 8631718
107 + 8631611 = 8631718
149 + 8631569 = 8631718
239 + 8631479 = 8631718
317 + 8631401 = 8631718

Showing the first eight; more decompositions exist.
