Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632656, here are decompositions:

7 + 8632649 = 8632656
47 + 8632609 = 8632656
59 + 8632597 = 8632656
83 + 8632573 = 8632656
127 + 8632529 = 8632656
163 + 8632493 = 8632656
167 + 8632489 = 8632656
199 + 8632457 = 8632656

Showing the first eight; more decompositions exist.
