Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72814, here are decompositions:
- 17 + 72797 = 72814
- 47 + 72767 = 72814
- 107 + 72707 = 72814
- 113 + 72701 = 72814
- 167 + 72647 = 72814
- 191 + 72623 = 72814
- 197 + 72617 = 72814
- 263 + 72551 = 72814
Showing the first eight; more decompositions exist.
