Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630646, here are decompositions:

5 + 8630641 = 8630646
7 + 8630639 = 8630646
47 + 8630599 = 8630646
53 + 8630593 = 8630646
127 + 8630519 = 8630646
163 + 8630483 = 8630646
197 + 8630449 = 8630646
229 + 8630417 = 8630646

Showing the first eight; more decompositions exist.
