Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135940, here are decompositions:

3 + 135937 = 135940
11 + 135929 = 135940
29 + 135911 = 135940
41 + 135899 = 135940
47 + 135893 = 135940
53 + 135887 = 135940
89 + 135851 = 135940
197 + 135743 = 135940

Showing the first eight; more decompositions exist.
