Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33664, here are decompositions:
- 17 + 33647 = 33664
- 23 + 33641 = 33664
- 41 + 33623 = 33664
- 47 + 33617 = 33664
- 83 + 33581 = 33664
- 101 + 33563 = 33664
- 131 + 33533 = 33664
- 251 + 33413 = 33664
Showing the first eight; more decompositions exist.
