Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630878, here are decompositions:

17 + 8630861 = 8630878
41 + 8630837 = 8630878
89 + 8630789 = 8630878
107 + 8630771 = 8630878
239 + 8630639 = 8630878
359 + 8630519 = 8630878
401 + 8630477 = 8630878
461 + 8630417 = 8630878

Showing the first eight; more decompositions exist.
