Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168328, here are decompositions:
- 5 + 168323 = 168328
- 47 + 168281 = 168328
- 59 + 168269 = 168328
- 101 + 168227 = 168328
- 131 + 168197 = 168328
- 239 + 168089 = 168328
- 257 + 168071 = 168328
- 449 + 167879 = 168328
Showing the first eight; more decompositions exist.
