Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686740, here are decompositions:

11 + 8686729 = 8686740
19 + 8686721 = 8686740
37 + 8686703 = 8686740
53 + 8686687 = 8686740
61 + 8686679 = 8686740
71 + 8686669 = 8686740
79 + 8686661 = 8686740
89 + 8686651 = 8686740

Showing the first eight; more decompositions exist.
