Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990530, here are decompositions:

7 + 990523 = 990530
19 + 990511 = 990530
43 + 990487 = 990530
61 + 990469 = 990530
67 + 990463 = 990530
181 + 990349 = 990530
199 + 990331 = 990530
223 + 990307 = 990530

Showing the first eight; more decompositions exist.
