Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631660, here are decompositions:

31 + 8631629 = 8631660
43 + 8631617 = 8631660
61 + 8631599 = 8631660
127 + 8631533 = 8631660
181 + 8631479 = 8631660
269 + 8631391 = 8631660
281 + 8631379 = 8631660
293 + 8631367 = 8631660

Showing the first eight; more decompositions exist.
