Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534438, here are decompositions:
- 11 + 31534427 = 31534438
- 137 + 31534301 = 31534438
- 167 + 31534271 = 31534438
- 191 + 31534247 = 31534438
- 197 + 31534241 = 31534438
- 239 + 31534199 = 31534438
- 251 + 31534187 = 31534438
- 269 + 31534169 = 31534438
Showing the first eight; more decompositions exist.
