Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68668, here are decompositions:
- 29 + 68639 = 68668
- 71 + 68597 = 68668
- 101 + 68567 = 68668
- 137 + 68531 = 68668
- 167 + 68501 = 68668
- 179 + 68489 = 68668
- 191 + 68477 = 68668
- 269 + 68399 = 68668
Showing the first eight; more decompositions exist.
