Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756840, here are decompositions:

3 + 8756837 = 8756840
151 + 8756689 = 8756840
163 + 8756677 = 8756840
181 + 8756659 = 8756840
283 + 8756557 = 8756840
307 + 8756533 = 8756840
331 + 8756509 = 8756840
439 + 8756401 = 8756840

Showing the first eight; more decompositions exist.
