Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656938, here are decompositions:

5 + 8656933 = 8656938
19 + 8656919 = 8656938
41 + 8656897 = 8656938
47 + 8656891 = 8656938
67 + 8656871 = 8656938
89 + 8656849 = 8656938
107 + 8656831 = 8656938
109 + 8656829 = 8656938

Showing the first eight; more decompositions exist.
