Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616786, here are decompositions:

5 + 8616781 = 8616786
23 + 8616763 = 8616786
29 + 8616757 = 8616786
53 + 8616733 = 8616786
67 + 8616719 = 8616786
83 + 8616703 = 8616786
97 + 8616689 = 8616786
107 + 8616679 = 8616786

Showing the first eight; more decompositions exist.
