Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657456, here are decompositions:

7 + 8657449 = 8657456
79 + 8657377 = 8657456
439 + 8657017 = 8657456
523 + 8656933 = 8657456
607 + 8656849 = 8657456
727 + 8656729 = 8657456
853 + 8656603 = 8657456
883 + 8656573 = 8657456

Showing the first eight; more decompositions exist.
