Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12822, here are decompositions:
- 13 + 12809 = 12822
- 23 + 12799 = 12822
- 31 + 12791 = 12822
- 41 + 12781 = 12822
- 59 + 12763 = 12822
- 79 + 12743 = 12822
- 83 + 12739 = 12822
- 101 + 12721 = 12822
Showing the first eight; more decompositions exist.
