Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67940, here are decompositions:

7 + 67933 = 67940
13 + 67927 = 67940
73 + 67867 = 67940
97 + 67843 = 67940
139 + 67801 = 67940
151 + 67789 = 67940
157 + 67783 = 67940
163 + 67777 = 67940

Showing the first eight; more decompositions exist.
