Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 346, here are decompositions:
- 29 + 317 = 346
- 53 + 293 = 346
- 83 + 263 = 346
- 89 + 257 = 346
- 107 + 239 = 346
- 113 + 233 = 346
- 149 + 197 = 346
- 167 + 179 = 346
Showing the first eight; more decompositions exist.
