Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143668, here are decompositions:
- 17 + 143651 = 143668
- 59 + 143609 = 143668
- 101 + 143567 = 143668
- 131 + 143537 = 143668
- 149 + 143519 = 143668
- 167 + 143501 = 143668
- 179 + 143489 = 143668
- 191 + 143477 = 143668
Showing the first eight; more decompositions exist.
