Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656178, here are decompositions:

7 + 8656171 = 8656178
19 + 8656159 = 8656178
31 + 8656147 = 8656178
61 + 8656117 = 8656178
109 + 8656069 = 8656178
211 + 8655967 = 8656178
241 + 8655937 = 8656178
277 + 8655901 = 8656178

Showing the first eight; more decompositions exist.
