Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659664, here are decompositions:

37 + 8659627 = 8659664
127 + 8659537 = 8659664
151 + 8659513 = 8659664
163 + 8659501 = 8659664
193 + 8659471 = 8659664
241 + 8659423 = 8659664
271 + 8659393 = 8659664
283 + 8659381 = 8659664

Showing the first eight; more decompositions exist.
