Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72772, here are decompositions:
- 5 + 72767 = 72772
- 53 + 72719 = 72772
- 71 + 72701 = 72772
- 83 + 72689 = 72772
- 101 + 72671 = 72772
- 149 + 72623 = 72772
- 239 + 72533 = 72772
- 269 + 72503 = 72772
Showing the first eight; more decompositions exist.
