Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990942, here are decompositions:

19 + 990923 = 990942
53 + 990889 = 990942
61 + 990881 = 990942
101 + 990841 = 990942
181 + 990761 = 990942
223 + 990719 = 990942
269 + 990673 = 990942
311 + 990631 = 990942

Showing the first eight; more decompositions exist.
