Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91168, here are decompositions:
- 5 + 91163 = 91168
- 17 + 91151 = 91168
- 29 + 91139 = 91168
- 41 + 91127 = 91168
- 47 + 91121 = 91168
- 71 + 91097 = 91168
- 89 + 91079 = 91168
- 149 + 91019 = 91168
Showing the first eight; more decompositions exist.
