Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656386, here are decompositions:

7 + 8656379 = 8656386
17 + 8656369 = 8656386
19 + 8656367 = 8656386
23 + 8656363 = 8656386
29 + 8656357 = 8656386
47 + 8656339 = 8656386
73 + 8656313 = 8656386
103 + 8656283 = 8656386

Showing the first eight; more decompositions exist.
