Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165260, here are decompositions:
- 13 + 165247 = 165260
- 31 + 165229 = 165260
- 79 + 165181 = 165260
- 127 + 165133 = 165260
- 157 + 165103 = 165260
- 181 + 165079 = 165260
- 211 + 165049 = 165260
- 223 + 165037 = 165260
Showing the first eight; more decompositions exist.
