Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526270, here are decompositions:
- 31 + 31526239 = 31526270
- 43 + 31526227 = 31526270
- 73 + 31526197 = 31526270
- 79 + 31526191 = 31526270
- 313 + 31525957 = 31526270
- 367 + 31525903 = 31526270
- 379 + 31525891 = 31526270
- 421 + 31525849 = 31526270
Showing the first eight; more decompositions exist.
