Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5666, here are decompositions:
- 7 + 5659 = 5666
- 13 + 5653 = 5666
- 19 + 5647 = 5666
- 43 + 5623 = 5666
- 97 + 5569 = 5666
- 103 + 5563 = 5666
- 109 + 5557 = 5666
- 139 + 5527 = 5666
Showing the first eight; more decompositions exist.
