Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657660, here are decompositions:

31 + 8657629 = 8657660
97 + 8657563 = 8657660
103 + 8657557 = 8657660
127 + 8657533 = 8657660
157 + 8657503 = 8657660
199 + 8657461 = 8657660
211 + 8657449 = 8657660
229 + 8657431 = 8657660

Showing the first eight; more decompositions exist.
