Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756646, here are decompositions:

13 + 8756633 = 8756646
23 + 8756623 = 8756646
37 + 8756609 = 8756646
53 + 8756593 = 8756646
79 + 8756567 = 8756646
89 + 8756557 = 8756646
113 + 8756533 = 8756646
127 + 8756519 = 8756646

Showing the first eight; more decompositions exist.
