Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756686, here are decompositions:

17 + 8756669 = 8756686
53 + 8756633 = 8756686
167 + 8756519 = 8756686
179 + 8756507 = 8756686
227 + 8756459 = 8756686
293 + 8756393 = 8756686
353 + 8756333 = 8756686
557 + 8756129 = 8756686

Showing the first eight; more decompositions exist.
