Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649690, here are decompositions:

13 + 8649677 = 8649690
19 + 8649671 = 8649690
29 + 8649661 = 8649690
53 + 8649637 = 8649690
61 + 8649629 = 8649690
67 + 8649623 = 8649690
79 + 8649611 = 8649690
109 + 8649581 = 8649690

Showing the first eight; more decompositions exist.
