Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682780, here are decompositions:

17 + 8682763 = 8682780
23 + 8682757 = 8682780
31 + 8682749 = 8682780
37 + 8682743 = 8682780
53 + 8682727 = 8682780
59 + 8682721 = 8682780
61 + 8682719 = 8682780
79 + 8682701 = 8682780

Showing the first eight; more decompositions exist.
