Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656242, here are decompositions:

11 + 8656231 = 8656242
53 + 8656189 = 8656242
71 + 8656171 = 8656242
73 + 8656169 = 8656242
79 + 8656163 = 8656242
83 + 8656159 = 8656242
109 + 8656133 = 8656242
113 + 8656129 = 8656242

Showing the first eight; more decompositions exist.
