Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617966, here are decompositions:

17 + 8617949 = 8617966
23 + 8617943 = 8617966
89 + 8617877 = 8617966
167 + 8617799 = 8617966
179 + 8617787 = 8617966
197 + 8617769 = 8617966
263 + 8617703 = 8617966
419 + 8617547 = 8617966

Showing the first eight; more decompositions exist.
