Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689690, here are decompositions:

3 + 8689687 = 8689690
17 + 8689673 = 8689690
29 + 8689661 = 8689690
41 + 8689649 = 8689690
47 + 8689643 = 8689690
137 + 8689553 = 8689690
197 + 8689493 = 8689690
227 + 8689463 = 8689690

Showing the first eight; more decompositions exist.
