Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17724, here are decompositions:
- 11 + 17713 = 17724
- 17 + 17707 = 17724
- 41 + 17683 = 17724
- 43 + 17681 = 17724
- 67 + 17657 = 17724
- 97 + 17627 = 17724
- 101 + 17623 = 17724
- 127 + 17597 = 17724
Showing the first eight; more decompositions exist.
