Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630670, here are decompositions:

7 + 8630663 = 8630670
17 + 8630653 = 8630670
23 + 8630647 = 8630670
29 + 8630641 = 8630670
31 + 8630639 = 8630670
71 + 8630599 = 8630670
79 + 8630591 = 8630670
151 + 8630519 = 8630670

Showing the first eight; more decompositions exist.
