Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667168, here are decompositions:
- 17 + 8667151 = 8667168
- 31 + 8667137 = 8667168
- 47 + 8667121 = 8667168
- 89 + 8667079 = 8667168
- 179 + 8666989 = 8667168
- 229 + 8666939 = 8667168
- 241 + 8666927 = 8667168
- 277 + 8666891 = 8667168
Showing the first eight; more decompositions exist.
