Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 358, here are decompositions:
- 5 + 353 = 358
- 11 + 347 = 358
- 41 + 317 = 358
- 47 + 311 = 358
- 89 + 269 = 358
- 101 + 257 = 358
- 107 + 251 = 358
- 131 + 227 = 358
Showing the first eight; more decompositions exist.
