Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009666, here are decompositions:

17 + 1009649 = 1009666
23 + 1009643 = 1009666
29 + 1009637 = 1009666
107 + 1009559 = 1009666
167 + 1009499 = 1009666
179 + 1009487 = 1009666
227 + 1009439 = 1009666
233 + 1009433 = 1009666

Showing the first eight; more decompositions exist.
