Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72958, here are decompositions:

5 + 72953 = 72958
47 + 72911 = 72958
89 + 72869 = 72958
191 + 72767 = 72958
239 + 72719 = 72958
251 + 72707 = 72958
257 + 72701 = 72958
269 + 72689 = 72958

Showing the first eight; more decompositions exist.
