Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656424, here are decompositions:

13 + 8656411 = 8656424
31 + 8656393 = 8656424
61 + 8656363 = 8656424
67 + 8656357 = 8656424
103 + 8656321 = 8656424
151 + 8656273 = 8656424
193 + 8656231 = 8656424
277 + 8656147 = 8656424

Showing the first eight; more decompositions exist.
