Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20922, here are decompositions:
- 19 + 20903 = 20922
- 23 + 20899 = 20922
- 43 + 20879 = 20922
- 73 + 20849 = 20922
- 113 + 20809 = 20922
- 149 + 20773 = 20922
- 151 + 20771 = 20922
- 163 + 20759 = 20922
Showing the first eight; more decompositions exist.
