Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630788, here are decompositions:

17 + 8630771 = 8630788
29 + 8630759 = 8630788
149 + 8630639 = 8630788
197 + 8630591 = 8630788
269 + 8630519 = 8630788
311 + 8630477 = 8630788
401 + 8630387 = 8630788
557 + 8630231 = 8630788

Showing the first eight; more decompositions exist.
