Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168268, here are decompositions:
- 5 + 168263 = 168268
- 41 + 168227 = 168268
- 71 + 168197 = 168268
- 179 + 168089 = 168268
- 197 + 168071 = 168268
- 239 + 168029 = 168268
- 281 + 167987 = 168268
- 389 + 167879 = 168268
Showing the first eight; more decompositions exist.
