Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656970, here are decompositions:

31 + 8656939 = 8656970
37 + 8656933 = 8656970
67 + 8656903 = 8656970
73 + 8656897 = 8656970
79 + 8656891 = 8656970
139 + 8656831 = 8656970
163 + 8656807 = 8656970
211 + 8656759 = 8656970

Showing the first eight; more decompositions exist.
