Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990540, here are decompositions:

11 + 990529 = 990540
17 + 990523 = 990540
29 + 990511 = 990540
37 + 990503 = 990540
43 + 990497 = 990540
53 + 990487 = 990540
71 + 990469 = 990540
151 + 990389 = 990540

Showing the first eight; more decompositions exist.
