Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756688, here are decompositions:

11 + 8756677 = 8756688
19 + 8756669 = 8756688
29 + 8756659 = 8756688
79 + 8756609 = 8756688
97 + 8756591 = 8756688
131 + 8756557 = 8756688
137 + 8756551 = 8756688
179 + 8756509 = 8756688

Showing the first eight; more decompositions exist.
