Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525786, here are decompositions:
- 3 + 31525783 = 31525786
- 23 + 31525763 = 31525786
- 137 + 31525649 = 31525786
- 179 + 31525607 = 31525786
- 197 + 31525589 = 31525786
- 233 + 31525553 = 31525786
- 389 + 31525397 = 31525786
- 419 + 31525367 = 31525786
Showing the first eight; more decompositions exist.
