Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634656, here are decompositions:

139 + 8634517 = 8634656
229 + 8634427 = 8634656
397 + 8634259 = 8634656
487 + 8634169 = 8634656
523 + 8634133 = 8634656
607 + 8634049 = 8634656
673 + 8633983 = 8634656
757 + 8633899 = 8634656

Showing the first eight; more decompositions exist.
