Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630816, here are decompositions:

3 + 8630813 = 8630816
37 + 8630779 = 8630816
67 + 8630749 = 8630816
79 + 8630737 = 8630816
163 + 8630653 = 8630816
223 + 8630593 = 8630816
367 + 8630449 = 8630816
373 + 8630443 = 8630816

Showing the first eight; more decompositions exist.
