Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72940, here are decompositions:

3 + 72937 = 72940
17 + 72923 = 72940
29 + 72911 = 72940
47 + 72893 = 72940
71 + 72869 = 72940
173 + 72767 = 72940
233 + 72707 = 72940
239 + 72701 = 72940

Showing the first eight; more decompositions exist.
