Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756560, here are decompositions:

3 + 8756557 = 8756560
41 + 8756519 = 8756560
53 + 8756507 = 8756560
89 + 8756471 = 8756560
101 + 8756459 = 8756560
167 + 8756393 = 8756560
179 + 8756381 = 8756560
227 + 8756333 = 8756560

Showing the first eight; more decompositions exist.
