Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13940, here are decompositions:

7 + 13933 = 13940
19 + 13921 = 13940
37 + 13903 = 13940
61 + 13879 = 13940
67 + 13873 = 13940
109 + 13831 = 13940
151 + 13789 = 13940
181 + 13759 = 13940

Showing the first eight; more decompositions exist.
