Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656170, here are decompositions:

7 + 8656163 = 8656170
11 + 8656159 = 8656170
23 + 8656147 = 8656170
37 + 8656133 = 8656170
41 + 8656129 = 8656170
53 + 8656117 = 8656170
73 + 8656097 = 8656170
79 + 8656091 = 8656170

Showing the first eight; more decompositions exist.
