Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91112, here are decompositions:
- 13 + 91099 = 91112
- 31 + 91081 = 91112
- 79 + 91033 = 91112
- 103 + 91009 = 91112
- 181 + 90931 = 91112
- 211 + 90901 = 91112
- 271 + 90841 = 91112
- 409 + 90703 = 91112
Showing the first eight; more decompositions exist.
