Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165760, here are decompositions:
- 11 + 165749 = 165760
- 41 + 165719 = 165760
- 47 + 165713 = 165760
- 53 + 165707 = 165760
- 59 + 165701 = 165760
- 107 + 165653 = 165760
- 149 + 165611 = 165760
- 173 + 165587 = 165760
Showing the first eight; more decompositions exist.
