Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545724, here are decompositions:
- 11 + 31545713 = 31545724
- 83 + 31545641 = 31545724
- 101 + 31545623 = 31545724
- 113 + 31545611 = 31545724
- 317 + 31545407 = 31545724
- 401 + 31545323 = 31545724
- 491 + 31545233 = 31545724
- 503 + 31545221 = 31545724
Showing the first eight; more decompositions exist.
