Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 368, here are decompositions:
- 19 + 349 = 368
- 31 + 337 = 368
- 37 + 331 = 368
- 61 + 307 = 368
- 97 + 271 = 368
- 127 + 241 = 368
- 139 + 229 = 368
- 157 + 211 = 368
Showing the first eight; more decompositions exist.
