Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656206, here are decompositions:

17 + 8656189 = 8656206
29 + 8656177 = 8656206
37 + 8656169 = 8656206
43 + 8656163 = 8656206
47 + 8656159 = 8656206
59 + 8656147 = 8656206
73 + 8656133 = 8656206
89 + 8656117 = 8656206

Showing the first eight; more decompositions exist.
