Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656392, here are decompositions:

13 + 8656379 = 8656392
23 + 8656369 = 8656392
29 + 8656363 = 8656392
53 + 8656339 = 8656392
71 + 8656321 = 8656392
79 + 8656313 = 8656392
109 + 8656283 = 8656392
113 + 8656279 = 8656392

Showing the first eight; more decompositions exist.
