Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008790, here are decompositions:

11 + 1008779 = 1008790
17 + 1008773 = 1008790
47 + 1008743 = 1008790
71 + 1008719 = 1008790
89 + 1008701 = 1008790
131 + 1008659 = 1008790
173 + 1008617 = 1008790
179 + 1008611 = 1008790

Showing the first eight; more decompositions exist.
