Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990560, here are decompositions:

13 + 990547 = 990560
31 + 990529 = 990560
37 + 990523 = 990560
73 + 990487 = 990560
97 + 990463 = 990560
163 + 990397 = 990560
199 + 990361 = 990560
211 + 990349 = 990560

Showing the first eight; more decompositions exist.
