Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656986, here are decompositions:

7 + 8656979 = 8656986
47 + 8656939 = 8656986
53 + 8656933 = 8656986
67 + 8656919 = 8656986
83 + 8656903 = 8656986
89 + 8656897 = 8656986
137 + 8656849 = 8656986
139 + 8656847 = 8656986

Showing the first eight; more decompositions exist.
