Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689966, here are decompositions:

17 + 8689949 = 8689966
23 + 8689943 = 8689966
113 + 8689853 = 8689966
149 + 8689817 = 8689966
167 + 8689799 = 8689966
239 + 8689727 = 8689966
293 + 8689673 = 8689966
317 + 8689649 = 8689966

Showing the first eight; more decompositions exist.
