Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656980, here are decompositions:

41 + 8656939 = 8656980
47 + 8656933 = 8656980
61 + 8656919 = 8656980
83 + 8656897 = 8656980
89 + 8656891 = 8656980
109 + 8656871 = 8656980
131 + 8656849 = 8656980
149 + 8656831 = 8656980

Showing the first eight; more decompositions exist.
