Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16940, here are decompositions:

3 + 16937 = 16940
13 + 16927 = 16940
19 + 16921 = 16940
37 + 16903 = 16940
61 + 16879 = 16940
97 + 16843 = 16940
109 + 16831 = 16940
181 + 16759 = 16940

Showing the first eight; more decompositions exist.
