Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656886, here are decompositions:

37 + 8656849 = 8656886
79 + 8656807 = 8656886
127 + 8656759 = 8656886
157 + 8656729 = 8656886
283 + 8656603 = 8656886
313 + 8656573 = 8656886
349 + 8656537 = 8656886
409 + 8656477 = 8656886

Showing the first eight; more decompositions exist.
