Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756666, here are decompositions:

7 + 8756659 = 8756666
13 + 8756653 = 8756666
43 + 8756623 = 8756666
73 + 8756593 = 8756666
109 + 8756557 = 8756666
157 + 8756509 = 8756666
229 + 8756437 = 8756666
349 + 8756317 = 8756666

Showing the first eight; more decompositions exist.
