Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39982, here are decompositions:

3 + 39979 = 39982
11 + 39971 = 39982
29 + 39953 = 39982
53 + 39929 = 39982
113 + 39869 = 39982
191 + 39791 = 39982
233 + 39749 = 39982
263 + 39719 = 39982

Showing the first eight; more decompositions exist.
