Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656664, here are decompositions:

61 + 8656603 = 8656664
103 + 8656561 = 8656664
127 + 8656537 = 8656664
241 + 8656423 = 8656664
271 + 8656393 = 8656664
307 + 8656357 = 8656664
433 + 8656231 = 8656664
487 + 8656177 = 8656664

Showing the first eight; more decompositions exist.
