Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756660, here are decompositions:

7 + 8756653 = 8756660
37 + 8756623 = 8756660
67 + 8756593 = 8756660
103 + 8756557 = 8756660
109 + 8756551 = 8756660
127 + 8756533 = 8756660
151 + 8756509 = 8756660
223 + 8756437 = 8756660

Showing the first eight; more decompositions exist.
