Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526138, here are decompositions:
- 157 + 31525981 = 31526138
- 181 + 31525957 = 31526138
- 211 + 31525927 = 31526138
- 229 + 31525909 = 31526138
- 367 + 31525771 = 31526138
- 421 + 31525717 = 31526138
- 439 + 31525699 = 31526138
- 487 + 31525651 = 31526138
Showing the first eight; more decompositions exist.
