Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990684, here are decompositions:

11 + 990673 = 990684
41 + 990643 = 990684
47 + 990637 = 990684
53 + 990631 = 990684
137 + 990547 = 990684
173 + 990511 = 990684
181 + 990503 = 990684
197 + 990487 = 990684

Showing the first eight; more decompositions exist.
