Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159868, here are decompositions:
- 11 + 159857 = 159868
- 29 + 159839 = 159868
- 89 + 159779 = 159868
- 131 + 159737 = 159868
- 167 + 159701 = 159868
- 197 + 159671 = 159868
- 239 + 159629 = 159868
- 251 + 159617 = 159868
Showing the first eight; more decompositions exist.
