Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990510, here are decompositions:

7 + 990503 = 990510
13 + 990497 = 990510
23 + 990487 = 990510
41 + 990469 = 990510
47 + 990463 = 990510
113 + 990397 = 990510
127 + 990383 = 990510
139 + 990371 = 990510

Showing the first eight; more decompositions exist.
