Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656922, here are decompositions:

3 + 8656919 = 8656922
19 + 8656903 = 8656922
31 + 8656891 = 8656922
73 + 8656849 = 8656922
163 + 8656759 = 8656922
193 + 8656729 = 8656922
349 + 8656573 = 8656922
499 + 8656423 = 8656922

Showing the first eight; more decompositions exist.
