Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165792, here are decompositions:
- 13 + 165779 = 165792
- 43 + 165749 = 165792
- 71 + 165721 = 165792
- 73 + 165719 = 165792
- 79 + 165713 = 165792
- 83 + 165709 = 165792
- 89 + 165703 = 165792
- 139 + 165653 = 165792
Showing the first eight; more decompositions exist.
