Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656164, here are decompositions:

5 + 8656159 = 8656164
17 + 8656147 = 8656164
31 + 8656133 = 8656164
47 + 8656117 = 8656164
67 + 8656097 = 8656164
71 + 8656093 = 8656164
73 + 8656091 = 8656164
107 + 8656057 = 8656164

Showing the first eight; more decompositions exist.
