Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168448, here are decompositions:
- 101 + 168347 = 168448
- 167 + 168281 = 168448
- 179 + 168269 = 168448
- 251 + 168197 = 168448
- 359 + 168089 = 168448
- 419 + 168029 = 168448
- 461 + 167987 = 168448
- 557 + 167891 = 168448
Showing the first eight; more decompositions exist.
