Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016866, here are decompositions:

17 + 1016849 = 1016866
23 + 1016843 = 1016866
83 + 1016783 = 1016866
89 + 1016777 = 1016866
269 + 1016597 = 1016866
293 + 1016573 = 1016866
443 + 1016423 = 1016866
467 + 1016399 = 1016866

Showing the first eight; more decompositions exist.
