Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756664, here are decompositions:

5 + 8756659 = 8756664
11 + 8756653 = 8756664
31 + 8756633 = 8756664
41 + 8756623 = 8756664
71 + 8756593 = 8756664
73 + 8756591 = 8756664
97 + 8756567 = 8756664
107 + 8756557 = 8756664

Showing the first eight; more decompositions exist.
