Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168078, here are decompositions:
- 7 + 168071 = 168078
- 11 + 168067 = 168078
- 41 + 168037 = 168078
- 107 + 167971 = 168078
- 167 + 167911 = 168078
- 179 + 167899 = 168078
- 191 + 167887 = 168078
- 199 + 167879 = 168078
Showing the first eight; more decompositions exist.
