Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68940, here are decompositions:
- 13 + 68927 = 68940
- 23 + 68917 = 68940
- 31 + 68909 = 68940
- 37 + 68903 = 68940
- 41 + 68899 = 68940
- 43 + 68897 = 68940
- 59 + 68881 = 68940
- 61 + 68879 = 68940
Showing the first eight; more decompositions exist.
