Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525724, here are decompositions:
- 7 + 31525717 = 31525724
- 37 + 31525687 = 31525724
- 67 + 31525657 = 31525724
- 73 + 31525651 = 31525724
- 157 + 31525567 = 31525724
- 277 + 31525447 = 31525724
- 457 + 31525267 = 31525724
- 463 + 31525261 = 31525724
Showing the first eight; more decompositions exist.
