Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625964, here are decompositions:

3 + 8625961 = 8625964
5 + 8625959 = 8625964
131 + 8625833 = 8625964
257 + 8625707 = 8625964
443 + 8625521 = 8625964
647 + 8625317 = 8625964
653 + 8625311 = 8625964
701 + 8625263 = 8625964

Showing the first eight; more decompositions exist.
