Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656908, here are decompositions:

5 + 8656903 = 8656908
11 + 8656897 = 8656908
17 + 8656891 = 8656908
37 + 8656871 = 8656908
59 + 8656849 = 8656908
61 + 8656847 = 8656908
79 + 8656829 = 8656908
101 + 8656807 = 8656908

Showing the first eight; more decompositions exist.
