Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6858, here are decompositions:
- 17 + 6841 = 6858
- 29 + 6829 = 6858
- 31 + 6827 = 6858
- 67 + 6791 = 6858
- 79 + 6779 = 6858
- 97 + 6761 = 6858
- 139 + 6719 = 6858
- 149 + 6709 = 6858
Showing the first eight; more decompositions exist.
