Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656894, here are decompositions:

3 + 8656891 = 8656894
23 + 8656871 = 8656894
47 + 8656847 = 8656894
107 + 8656787 = 8656894
167 + 8656727 = 8656894
173 + 8656721 = 8656894
227 + 8656667 = 8656894
317 + 8656577 = 8656894

Showing the first eight; more decompositions exist.
