Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165270, here are decompositions:
- 23 + 165247 = 165270
- 37 + 165233 = 165270
- 41 + 165229 = 165270
- 59 + 165211 = 165270
- 67 + 165203 = 165270
- 89 + 165181 = 165270
- 97 + 165173 = 165270
- 109 + 165161 = 165270
Showing the first eight; more decompositions exist.
