Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5668, here are decompositions:
- 11 + 5657 = 5668
- 17 + 5651 = 5668
- 29 + 5639 = 5668
- 137 + 5531 = 5668
- 149 + 5519 = 5668
- 167 + 5501 = 5668
- 191 + 5477 = 5668
- 197 + 5471 = 5668
Showing the first eight; more decompositions exist.
