Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91164, here are decompositions:
- 5 + 91159 = 91164
- 11 + 91153 = 91164
- 13 + 91151 = 91164
- 23 + 91141 = 91164
- 37 + 91127 = 91164
- 43 + 91121 = 91164
- 67 + 91097 = 91164
- 83 + 91081 = 91164
Showing the first eight; more decompositions exist.
