Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990956, here are decompositions:

3 + 990953 = 990956
67 + 990889 = 990956
157 + 990799 = 990956
223 + 990733 = 990956
283 + 990673 = 990956
313 + 990643 = 990956
367 + 990589 = 990956
397 + 990559 = 990956

Showing the first eight; more decompositions exist.
