Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13668, here are decompositions:
- 19 + 13649 = 13668
- 41 + 13627 = 13668
- 71 + 13597 = 13668
- 101 + 13567 = 13668
- 131 + 13537 = 13668
- 181 + 13487 = 13668
- 191 + 13477 = 13668
- 199 + 13469 = 13668
Showing the first eight; more decompositions exist.
