Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31344, here are decompositions:
- 7 + 31337 = 31344
- 11 + 31333 = 31344
- 17 + 31327 = 31344
- 23 + 31321 = 31344
- 37 + 31307 = 31344
- 67 + 31277 = 31344
- 73 + 31271 = 31344
- 97 + 31247 = 31344
Showing the first eight; more decompositions exist.
