Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165926, here are decompositions:
- 43 + 165883 = 165926
- 97 + 165829 = 165926
- 109 + 165817 = 165926
- 127 + 165799 = 165926
- 223 + 165703 = 165926
- 337 + 165589 = 165926
- 367 + 165559 = 165926
- 373 + 165553 = 165926
Showing the first eight; more decompositions exist.
