Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990984, here are decompositions:

11 + 990973 = 990984
17 + 990967 = 990984
23 + 990961 = 990984
31 + 990953 = 990984
61 + 990923 = 990984
67 + 990917 = 990984
97 + 990887 = 990984
103 + 990881 = 990984

Showing the first eight; more decompositions exist.
