Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168658, here are decompositions:
- 29 + 168629 = 168658
- 41 + 168617 = 168658
- 59 + 168599 = 168658
- 131 + 168527 = 168658
- 167 + 168491 = 168658
- 311 + 168347 = 168658
- 389 + 168269 = 168658
- 431 + 168227 = 168658
Showing the first eight; more decompositions exist.
