Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165928, here are decompositions:
- 41 + 165887 = 165928
- 71 + 165857 = 165928
- 149 + 165779 = 165928
- 179 + 165749 = 165928
- 227 + 165701 = 165928
- 311 + 165617 = 165928
- 317 + 165611 = 165928
- 359 + 165569 = 165928
Showing the first eight; more decompositions exist.
