Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545794, here are decompositions:
- 31 + 31545763 = 31545794
- 127 + 31545667 = 31545794
- 307 + 31545487 = 31545794
- 421 + 31545373 = 31545794
- 463 + 31545331 = 31545794
- 613 + 31545181 = 31545794
- 727 + 31545067 = 31545794
- 733 + 31545061 = 31545794
Showing the first eight; more decompositions exist.
