Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990558, here are decompositions:

11 + 990547 = 990558
29 + 990529 = 990558
47 + 990511 = 990558
61 + 990497 = 990558
71 + 990487 = 990558
89 + 990469 = 990558
181 + 990377 = 990558
197 + 990361 = 990558

Showing the first eight; more decompositions exist.
