Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6822, here are decompositions:
- 19 + 6803 = 6822
- 29 + 6793 = 6822
- 31 + 6791 = 6822
- 41 + 6781 = 6822
- 43 + 6779 = 6822
- 59 + 6763 = 6822
- 61 + 6761 = 6822
- 89 + 6733 = 6822
Showing the first eight; more decompositions exist.
