Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656208, here are decompositions:

19 + 8656189 = 8656208
31 + 8656177 = 8656208
37 + 8656171 = 8656208
61 + 8656147 = 8656208
79 + 8656129 = 8656208
139 + 8656069 = 8656208
151 + 8656057 = 8656208
241 + 8655967 = 8656208

Showing the first eight; more decompositions exist.
