Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40982, here are decompositions:

43 + 40939 = 40982
79 + 40903 = 40982
103 + 40879 = 40982
163 + 40819 = 40982
181 + 40801 = 40982
211 + 40771 = 40982
223 + 40759 = 40982
283 + 40699 = 40982

Showing the first eight; more decompositions exist.
