Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68808, here are decompositions:
- 17 + 68791 = 68808
- 31 + 68777 = 68808
- 37 + 68771 = 68808
- 41 + 68767 = 68808
- 59 + 68749 = 68808
- 71 + 68737 = 68808
- 79 + 68729 = 68808
- 97 + 68711 = 68808
Showing the first eight; more decompositions exist.
