Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990066, here are decompositions:

13 + 990053 = 990066
23 + 990043 = 990066
29 + 990037 = 990066
43 + 990023 = 990066
53 + 990013 = 990066
67 + 989999 = 990066
89 + 989977 = 990066
107 + 989959 = 990066

Showing the first eight; more decompositions exist.
