Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656942, here are decompositions:

3 + 8656939 = 8656942
23 + 8656919 = 8656942
71 + 8656871 = 8656942
113 + 8656829 = 8656942
251 + 8656691 = 8656942
353 + 8656589 = 8656942
419 + 8656523 = 8656942
431 + 8656511 = 8656942

Showing the first eight; more decompositions exist.
