Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33720, here are decompositions:
- 7 + 33713 = 33720
- 17 + 33703 = 33720
- 41 + 33679 = 33720
- 73 + 33647 = 33720
- 79 + 33641 = 33720
- 83 + 33637 = 33720
- 97 + 33623 = 33720
- 101 + 33619 = 33720
Showing the first eight; more decompositions exist.
