Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165748, here are decompositions:
- 29 + 165719 = 165748
- 41 + 165707 = 165748
- 47 + 165701 = 165748
- 131 + 165617 = 165748
- 137 + 165611 = 165748
- 179 + 165569 = 165748
- 197 + 165551 = 165748
- 269 + 165479 = 165748
Showing the first eight; more decompositions exist.
