Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91124, here are decompositions:
- 3 + 91121 = 91124
- 43 + 91081 = 91124
- 127 + 90997 = 91124
- 193 + 90931 = 91124
- 223 + 90901 = 91124
- 277 + 90847 = 91124
- 283 + 90841 = 91124
- 331 + 90793 = 91124
Showing the first eight; more decompositions exist.
