Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616780, here are decompositions:

17 + 8616763 = 8616780
19 + 8616761 = 8616780
23 + 8616757 = 8616780
47 + 8616733 = 8616780
59 + 8616721 = 8616780
61 + 8616719 = 8616780
89 + 8616691 = 8616780
101 + 8616679 = 8616780

Showing the first eight; more decompositions exist.
