Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630812, here are decompositions:

23 + 8630789 = 8630812
41 + 8630771 = 8630812
53 + 8630759 = 8630812
149 + 8630663 = 8630812
173 + 8630639 = 8630812
293 + 8630519 = 8630812
521 + 8630291 = 8630812
563 + 8630249 = 8630812

Showing the first eight; more decompositions exist.
