Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043666, here are decompositions:

3 + 1043663 = 1043666
67 + 1043599 = 1043666
73 + 1043593 = 1043666
79 + 1043587 = 1043666
109 + 1043557 = 1043666
199 + 1043467 = 1043666
367 + 1043299 = 1043666
373 + 1043293 = 1043666

Showing the first eight; more decompositions exist.
