Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656856, here are decompositions:

7 + 8656849 = 8656856
97 + 8656759 = 8656856
127 + 8656729 = 8656856
283 + 8656573 = 8656856
379 + 8656477 = 8656856
433 + 8656423 = 8656856
457 + 8656399 = 8656856
463 + 8656393 = 8656856

Showing the first eight; more decompositions exist.
