Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68942, here are decompositions:
- 43 + 68899 = 68942
- 61 + 68881 = 68942
- 79 + 68863 = 68942
- 151 + 68791 = 68942
- 193 + 68749 = 68942
- 199 + 68743 = 68942
- 229 + 68713 = 68942
- 283 + 68659 = 68942
Showing the first eight; more decompositions exist.
