Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165308, here are decompositions:
- 61 + 165247 = 165308
- 79 + 165229 = 165308
- 97 + 165211 = 165308
- 127 + 165181 = 165308
- 229 + 165079 = 165308
- 271 + 165037 = 165308
- 307 + 165001 = 165308
- 397 + 164911 = 165308
Showing the first eight; more decompositions exist.
