Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009660, here are decompositions:

11 + 1009649 = 1009660
17 + 1009643 = 1009660
23 + 1009637 = 1009660
59 + 1009601 = 1009660
101 + 1009559 = 1009660
173 + 1009487 = 1009660
227 + 1009433 = 1009660
317 + 1009343 = 1009660

Showing the first eight; more decompositions exist.
