Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656236, here are decompositions:

5 + 8656231 = 8656236
47 + 8656189 = 8656236
59 + 8656177 = 8656236
67 + 8656169 = 8656236
73 + 8656163 = 8656236
89 + 8656147 = 8656236
103 + 8656133 = 8656236
107 + 8656129 = 8656236

Showing the first eight; more decompositions exist.
