Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756720, here are decompositions:

13 + 8756707 = 8756720
31 + 8756689 = 8756720
43 + 8756677 = 8756720
61 + 8756659 = 8756720
67 + 8756653 = 8756720
97 + 8756623 = 8756720
127 + 8756593 = 8756720
163 + 8756557 = 8756720

Showing the first eight; more decompositions exist.
