Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15922, here are decompositions:
- 3 + 15919 = 15922
- 41 + 15881 = 15922
- 113 + 15809 = 15922
- 131 + 15791 = 15922
- 149 + 15773 = 15922
- 173 + 15749 = 15922
- 191 + 15731 = 15922
- 239 + 15683 = 15922
Showing the first eight; more decompositions exist.
