Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656784, here are decompositions:

181 + 8656603 = 8656784
211 + 8656573 = 8656784
223 + 8656561 = 8656784
307 + 8656477 = 8656784
373 + 8656411 = 8656784
421 + 8656363 = 8656784
463 + 8656321 = 8656784
607 + 8656177 = 8656784

Showing the first eight; more decompositions exist.
