Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637660, here are decompositions:

19 + 8637641 = 8637660
23 + 8637637 = 8637660
41 + 8637619 = 8637660
43 + 8637617 = 8637660
137 + 8637523 = 8637660
139 + 8637521 = 8637660
151 + 8637509 = 8637660
167 + 8637493 = 8637660

Showing the first eight; more decompositions exist.
