Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990812, here are decompositions:

3 + 990809 = 990812
13 + 990799 = 990812
79 + 990733 = 990812
139 + 990673 = 990812
181 + 990631 = 990812
223 + 990589 = 990812
283 + 990529 = 990812
349 + 990463 = 990812

Showing the first eight; more decompositions exist.
