Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657256, here are decompositions:

7 + 8657249 = 8657256
17 + 8657239 = 8657256
19 + 8657237 = 8657256
239 + 8657017 = 8657256
277 + 8656979 = 8657256
317 + 8656939 = 8657256
337 + 8656919 = 8657256
353 + 8656903 = 8657256

Showing the first eight; more decompositions exist.
