Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159808, here are decompositions:
- 17 + 159791 = 159808
- 29 + 159779 = 159808
- 71 + 159737 = 159808
- 101 + 159707 = 159808
- 107 + 159701 = 159808
- 137 + 159671 = 159808
- 179 + 159629 = 159808
- 191 + 159617 = 159808
Showing the first eight; more decompositions exist.
