Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525970, here are decompositions:
- 13 + 31525957 = 31525970
- 19 + 31525951 = 31525970
- 43 + 31525927 = 31525970
- 61 + 31525909 = 31525970
- 67 + 31525903 = 31525970
- 79 + 31525891 = 31525970
- 193 + 31525777 = 31525970
- 199 + 31525771 = 31525970
Showing the first eight; more decompositions exist.
