Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20822, here are decompositions:
- 13 + 20809 = 20822
- 73 + 20749 = 20822
- 79 + 20743 = 20822
- 103 + 20719 = 20822
- 181 + 20641 = 20822
- 211 + 20611 = 20822
- 223 + 20599 = 20822
- 229 + 20593 = 20822
Showing the first eight; more decompositions exist.
