Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990680, here are decompositions:

7 + 990673 = 990680
37 + 990643 = 990680
43 + 990637 = 990680
151 + 990529 = 990680
157 + 990523 = 990680
193 + 990487 = 990680
211 + 990469 = 990680
283 + 990397 = 990680

Showing the first eight; more decompositions exist.
