Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990846, here are decompositions:

5 + 990841 = 990846
37 + 990809 = 990846
47 + 990799 = 990846
79 + 990767 = 990846
113 + 990733 = 990846
127 + 990719 = 990846
139 + 990707 = 990846
173 + 990673 = 990846

Showing the first eight; more decompositions exist.
