Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655690, here are decompositions:

11 + 8655679 = 8655690
13 + 8655677 = 8655690
19 + 8655671 = 8655690
37 + 8655653 = 8655690
41 + 8655649 = 8655690
53 + 8655637 = 8655690
59 + 8655631 = 8655690
61 + 8655629 = 8655690

Showing the first eight; more decompositions exist.
