Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990516, here are decompositions:

5 + 990511 = 990516
13 + 990503 = 990516
19 + 990497 = 990516
29 + 990487 = 990516
47 + 990469 = 990516
53 + 990463 = 990516
127 + 990389 = 990516
139 + 990377 = 990516

Showing the first eight; more decompositions exist.
