Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168432, here are decompositions:
- 23 + 168409 = 168432
- 41 + 168391 = 168432
- 79 + 168353 = 168432
- 101 + 168331 = 168432
- 109 + 168323 = 168432
- 139 + 168293 = 168432
- 151 + 168281 = 168432
- 163 + 168269 = 168432
Showing the first eight; more decompositions exist.
