Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39940, here are decompositions:

3 + 39937 = 39940
11 + 39929 = 39940
53 + 39887 = 39940
71 + 39869 = 39940
83 + 39857 = 39940
101 + 39839 = 39940
113 + 39827 = 39940
149 + 39791 = 39940

Showing the first eight; more decompositions exist.
