Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33660, here are decompositions:
- 13 + 33647 = 33660
- 19 + 33641 = 33660
- 23 + 33637 = 33660
- 31 + 33629 = 33660
- 37 + 33623 = 33660
- 41 + 33619 = 33660
- 43 + 33617 = 33660
- 47 + 33613 = 33660
Showing the first eight; more decompositions exist.
