Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13722, here are decompositions:
- 11 + 13711 = 13722
- 13 + 13709 = 13722
- 29 + 13693 = 13722
- 31 + 13691 = 13722
- 41 + 13681 = 13722
- 43 + 13679 = 13722
- 53 + 13669 = 13722
- 73 + 13649 = 13722
Showing the first eight; more decompositions exist.
