Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68748, here are decompositions:
- 5 + 68743 = 68748
- 11 + 68737 = 68748
- 19 + 68729 = 68748
- 37 + 68711 = 68748
- 61 + 68687 = 68748
- 79 + 68669 = 68748
- 89 + 68659 = 68748
- 109 + 68639 = 68748
Showing the first eight; more decompositions exist.
