Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31164, here are decompositions:
- 5 + 31159 = 31164
- 11 + 31153 = 31164
- 13 + 31151 = 31164
- 17 + 31147 = 31164
- 41 + 31123 = 31164
- 43 + 31121 = 31164
- 73 + 31091 = 31164
- 83 + 31081 = 31164
Showing the first eight; more decompositions exist.
