Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668168, here are decompositions:
- 11 + 8668157 = 8668168
- 17 + 8668151 = 8668168
- 101 + 8668067 = 8668168
- 107 + 8668061 = 8668168
- 137 + 8668031 = 8668168
- 167 + 8668001 = 8668168
- 239 + 8667929 = 8668168
- 269 + 8667899 = 8668168
Showing the first eight; more decompositions exist.
