Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631628, here are decompositions:

11 + 8631617 = 8631628
17 + 8631611 = 8631628
29 + 8631599 = 8631628
59 + 8631569 = 8631628
149 + 8631479 = 8631628
227 + 8631401 = 8631628
359 + 8631269 = 8631628
461 + 8631167 = 8631628

Showing the first eight; more decompositions exist.
