Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 304, here are decompositions:
- 11 + 293 = 304
- 23 + 281 = 304
- 41 + 263 = 304
- 47 + 257 = 304
- 53 + 251 = 304
- 71 + 233 = 304
- 107 + 197 = 304
- 113 + 191 = 304
Showing the first eight; more decompositions exist.
