Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656194, here are decompositions:

5 + 8656189 = 8656194
17 + 8656177 = 8656194
23 + 8656171 = 8656194
31 + 8656163 = 8656194
47 + 8656147 = 8656194
61 + 8656133 = 8656194
97 + 8656097 = 8656194
101 + 8656093 = 8656194

Showing the first eight; more decompositions exist.
