Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 324, here are decompositions:
- 7 + 317 = 324
- 11 + 313 = 324
- 13 + 311 = 324
- 17 + 307 = 324
- 31 + 293 = 324
- 41 + 283 = 324
- 43 + 281 = 324
- 47 + 277 = 324
Showing the first eight; more decompositions exist.
