Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637672, here are decompositions:

5 + 8637667 = 8637672
31 + 8637641 = 8637672
53 + 8637619 = 8637672
61 + 8637611 = 8637672
149 + 8637523 = 8637672
151 + 8637521 = 8637672
163 + 8637509 = 8637672
179 + 8637493 = 8637672

Showing the first eight; more decompositions exist.
