Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990822, here are decompositions:

13 + 990809 = 990822
23 + 990799 = 990822
61 + 990761 = 990822
89 + 990733 = 990822
103 + 990719 = 990822
149 + 990673 = 990822
179 + 990643 = 990822
191 + 990631 = 990822

Showing the first eight; more decompositions exist.
