Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 316, here are decompositions:
- 3 + 313 = 316
- 5 + 311 = 316
- 23 + 293 = 316
- 47 + 269 = 316
- 53 + 263 = 316
- 59 + 257 = 316
- 83 + 233 = 316
- 89 + 227 = 316
Showing the first eight; more decompositions exist.
