Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13740, here are decompositions:
- 11 + 13729 = 13740
- 17 + 13723 = 13740
- 19 + 13721 = 13740
- 29 + 13711 = 13740
- 31 + 13709 = 13740
- 43 + 13697 = 13740
- 47 + 13693 = 13740
- 53 + 13687 = 13740
Showing the first eight; more decompositions exist.
