Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631652, here are decompositions:

23 + 8631629 = 8631652
41 + 8631611 = 8631652
53 + 8631599 = 8631652
83 + 8631569 = 8631652
173 + 8631479 = 8631652
251 + 8631401 = 8631652
311 + 8631341 = 8631652
383 + 8631269 = 8631652

Showing the first eight; more decompositions exist.
