Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72916, here are decompositions:

5 + 72911 = 72916
23 + 72893 = 72916
47 + 72869 = 72916
149 + 72767 = 72916
197 + 72719 = 72916
227 + 72689 = 72916
269 + 72647 = 72916
293 + 72623 = 72916

Showing the first eight; more decompositions exist.
