Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756864, here are decompositions:

157 + 8756707 = 8756864
211 + 8756653 = 8756864
241 + 8756623 = 8756864
271 + 8756593 = 8756864
307 + 8756557 = 8756864
313 + 8756551 = 8756864
331 + 8756533 = 8756864
463 + 8756401 = 8756864

Showing the first eight; more decompositions exist.
