Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72790, here are decompositions:
- 23 + 72767 = 72790
- 71 + 72719 = 72790
- 83 + 72707 = 72790
- 89 + 72701 = 72790
- 101 + 72689 = 72790
- 167 + 72623 = 72790
- 173 + 72617 = 72790
- 239 + 72551 = 72790
Showing the first eight; more decompositions exist.
