Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630998, here are decompositions:

137 + 8630861 = 8630998
227 + 8630771 = 8630998
239 + 8630759 = 8630998
359 + 8630639 = 8630998
479 + 8630519 = 8630998
521 + 8630477 = 8630998
797 + 8630201 = 8630998
821 + 8630177 = 8630998

Showing the first eight; more decompositions exist.
