Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5688, here are decompositions:
- 5 + 5683 = 5688
- 19 + 5669 = 5688
- 29 + 5659 = 5688
- 31 + 5657 = 5688
- 37 + 5651 = 5688
- 41 + 5647 = 5688
- 47 + 5641 = 5688
- 97 + 5591 = 5688
Showing the first eight; more decompositions exist.
