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.
