Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72874, here are decompositions:

3 + 72871 = 72874
5 + 72869 = 72874
107 + 72767 = 72874
167 + 72707 = 72874
173 + 72701 = 72874
227 + 72647 = 72874
251 + 72623 = 72874
257 + 72617 = 72874

Showing the first eight; more decompositions exist.
