Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165768, here are decompositions:
- 19 + 165749 = 165768
- 47 + 165721 = 165768
- 59 + 165709 = 165768
- 61 + 165707 = 165768
- 67 + 165701 = 165768
- 101 + 165667 = 165768
- 151 + 165617 = 165768
- 157 + 165611 = 165768
Showing the first eight; more decompositions exist.
