Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159968, here are decompositions:
- 31 + 159937 = 159968
- 37 + 159931 = 159968
- 97 + 159871 = 159968
- 157 + 159811 = 159968
- 181 + 159787 = 159968
- 199 + 159769 = 159968
- 229 + 159739 = 159968
- 271 + 159697 = 159968
Showing the first eight; more decompositions exist.
