Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655786, here are decompositions:

17 + 8655769 = 8655786
37 + 8655749 = 8655786
47 + 8655739 = 8655786
53 + 8655733 = 8655786
67 + 8655719 = 8655786
79 + 8655707 = 8655786
107 + 8655679 = 8655786
109 + 8655677 = 8655786

Showing the first eight; more decompositions exist.
