Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655684, here are decompositions:

5 + 8655679 = 8655684
7 + 8655677 = 8655684
13 + 8655671 = 8655684
31 + 8655653 = 8655684
43 + 8655641 = 8655684
47 + 8655637 = 8655684
53 + 8655631 = 8655684
61 + 8655623 = 8655684

Showing the first eight; more decompositions exist.
