Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68740, here are decompositions:
- 3 + 68737 = 68740
- 11 + 68729 = 68740
- 29 + 68711 = 68740
- 41 + 68699 = 68740
- 53 + 68687 = 68740
- 71 + 68669 = 68740
- 101 + 68639 = 68740
- 107 + 68633 = 68740
Showing the first eight; more decompositions exist.
