Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631672, here are decompositions:

13 + 8631659 = 8631672
43 + 8631629 = 8631672
61 + 8631611 = 8631672
73 + 8631599 = 8631672
103 + 8631569 = 8631672
139 + 8631533 = 8631672
173 + 8631499 = 8631672
193 + 8631479 = 8631672

Showing the first eight; more decompositions exist.
