Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990692, here are decompositions:

19 + 990673 = 990692
61 + 990631 = 990692
103 + 990589 = 990692
163 + 990529 = 990692
181 + 990511 = 990692
223 + 990469 = 990692
229 + 990463 = 990692
331 + 990361 = 990692

Showing the first eight; more decompositions exist.
