Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525720, here are decompositions:
- 3 + 31525717 = 31525720
- 71 + 31525649 = 31525720
- 113 + 31525607 = 31525720
- 131 + 31525589 = 31525720
- 167 + 31525553 = 31525720
- 353 + 31525367 = 31525720
- 389 + 31525331 = 31525720
- 431 + 31525289 = 31525720
Showing the first eight; more decompositions exist.
