Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656982, here are decompositions:

3 + 8656979 = 8656982
43 + 8656939 = 8656982
79 + 8656903 = 8656982
151 + 8656831 = 8656982
181 + 8656801 = 8656982
223 + 8656759 = 8656982
379 + 8656603 = 8656982
409 + 8656573 = 8656982

Showing the first eight; more decompositions exist.
