Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990548, here are decompositions:

19 + 990529 = 990548
37 + 990511 = 990548
61 + 990487 = 990548
79 + 990469 = 990548
151 + 990397 = 990548
199 + 990349 = 990548
241 + 990307 = 990548
271 + 990277 = 990548

Showing the first eight; more decompositions exist.
