Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13724, here are decompositions:
- 3 + 13721 = 13724
- 13 + 13711 = 13724
- 31 + 13693 = 13724
- 37 + 13687 = 13724
- 43 + 13681 = 13724
- 97 + 13627 = 13724
- 127 + 13597 = 13724
- 157 + 13567 = 13724
Showing the first eight; more decompositions exist.
