Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 344, here are decompositions:
- 7 + 337 = 344
- 13 + 331 = 344
- 31 + 313 = 344
- 37 + 307 = 344
- 61 + 283 = 344
- 67 + 277 = 344
- 73 + 271 = 344
- 103 + 241 = 344
Showing the first eight; more decompositions exist.
