Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31822, here are decompositions:
- 5 + 31817 = 31822
- 23 + 31799 = 31822
- 29 + 31793 = 31822
- 53 + 31769 = 31822
- 71 + 31751 = 31822
- 101 + 31721 = 31822
- 173 + 31649 = 31822
- 179 + 31643 = 31822
Showing the first eight; more decompositions exist.
