Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5712, here are decompositions:
- 11 + 5701 = 5712
- 19 + 5693 = 5712
- 23 + 5689 = 5712
- 29 + 5683 = 5712
- 43 + 5669 = 5712
- 53 + 5659 = 5712
- 59 + 5653 = 5712
- 61 + 5651 = 5712
Showing the first eight; more decompositions exist.
