Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133768, here are decompositions:
- 59 + 133709 = 133768
- 71 + 133697 = 133768
- 137 + 133631 = 133768
- 197 + 133571 = 133768
- 227 + 133541 = 133768
- 269 + 133499 = 133768
- 317 + 133451 = 133768
- 389 + 133379 = 133768
Showing the first eight; more decompositions exist.
