Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526018, here are decompositions:
- 37 + 31525981 = 31526018
- 61 + 31525957 = 31526018
- 67 + 31525951 = 31526018
- 109 + 31525909 = 31526018
- 127 + 31525891 = 31526018
- 241 + 31525777 = 31526018
- 331 + 31525687 = 31526018
- 367 + 31525651 = 31526018
Showing the first eight; more decompositions exist.
