Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 310, here are decompositions:
- 3 + 307 = 310
- 17 + 293 = 310
- 29 + 281 = 310
- 41 + 269 = 310
- 47 + 263 = 310
- 53 + 257 = 310
- 59 + 251 = 310
- 71 + 239 = 310
Showing the first eight; more decompositions exist.
