Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656212, here are decompositions:

23 + 8656189 = 8656212
41 + 8656171 = 8656212
43 + 8656169 = 8656212
53 + 8656159 = 8656212
79 + 8656133 = 8656212
83 + 8656129 = 8656212
179 + 8656033 = 8656212
181 + 8656031 = 8656212

Showing the first eight; more decompositions exist.
