Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545582, here are decompositions:
- 83 + 31545499 = 31545582
- 113 + 31545469 = 31545582
- 181 + 31545401 = 31545582
- 191 + 31545391 = 31545582
- 239 + 31545343 = 31545582
- 251 + 31545331 = 31545582
- 283 + 31545299 = 31545582
- 349 + 31545233 = 31545582
Showing the first eight; more decompositions exist.
