Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631658, here are decompositions:

29 + 8631629 = 8631658
41 + 8631617 = 8631658
47 + 8631611 = 8631658
59 + 8631599 = 8631658
89 + 8631569 = 8631658
179 + 8631479 = 8631658
257 + 8631401 = 8631658
317 + 8631341 = 8631658

Showing the first eight; more decompositions exist.
