Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656718, here are decompositions:

157 + 8656561 = 8656718
181 + 8656537 = 8656718
241 + 8656477 = 8656718
307 + 8656411 = 8656718
349 + 8656369 = 8656718
379 + 8656339 = 8656718
397 + 8656321 = 8656718
439 + 8656279 = 8656718

Showing the first eight; more decompositions exist.
