Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689686, here are decompositions:

13 + 8689673 = 8689686
29 + 8689657 = 8689686
37 + 8689649 = 8689686
43 + 8689643 = 8689686
59 + 8689627 = 8689686
113 + 8689573 = 8689686
149 + 8689537 = 8689686
157 + 8689529 = 8689686

Showing the first eight; more decompositions exist.
