Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656916, here are decompositions:

13 + 8656903 = 8656916
19 + 8656897 = 8656916
67 + 8656849 = 8656916
109 + 8656807 = 8656916
157 + 8656759 = 8656916
313 + 8656603 = 8656916
379 + 8656537 = 8656916
439 + 8656477 = 8656916

Showing the first eight; more decompositions exist.
