Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656924, here are decompositions:

5 + 8656919 = 8656924
53 + 8656871 = 8656924
137 + 8656787 = 8656924
191 + 8656733 = 8656924
197 + 8656727 = 8656924
233 + 8656691 = 8656924
257 + 8656667 = 8656924
347 + 8656577 = 8656924

Showing the first eight; more decompositions exist.
