Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657008, here are decompositions:

29 + 8656979 = 8657008
89 + 8656919 = 8657008
137 + 8656871 = 8657008
179 + 8656829 = 8657008
281 + 8656727 = 8657008
317 + 8656691 = 8657008
419 + 8656589 = 8657008
431 + 8656577 = 8657008

Showing the first eight; more decompositions exist.
