Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31922, here are decompositions:
- 31 + 31891 = 31922
- 73 + 31849 = 31922
- 151 + 31771 = 31922
- 181 + 31741 = 31922
- 193 + 31729 = 31922
- 199 + 31723 = 31922
- 223 + 31699 = 31922
- 349 + 31573 = 31922
Showing the first eight; more decompositions exist.
