Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 306, here are decompositions:
- 13 + 293 = 306
- 23 + 283 = 306
- 29 + 277 = 306
- 37 + 269 = 306
- 43 + 263 = 306
- 67 + 239 = 306
- 73 + 233 = 306
- 79 + 227 = 306
Showing the first eight; more decompositions exist.
