Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689736, here are decompositions:

7 + 8689729 = 8689736
79 + 8689657 = 8689736
109 + 8689627 = 8689736
127 + 8689609 = 8689736
163 + 8689573 = 8689736
193 + 8689543 = 8689736
199 + 8689537 = 8689736
283 + 8689453 = 8689736

Showing the first eight; more decompositions exist.
