Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68746, here are decompositions:
- 3 + 68743 = 68746
- 17 + 68729 = 68746
- 47 + 68699 = 68746
- 59 + 68687 = 68746
- 107 + 68639 = 68746
- 113 + 68633 = 68746
- 149 + 68597 = 68746
- 179 + 68567 = 68746
Showing the first eight; more decompositions exist.
