Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526284, here are decompositions:
- 3 + 31526281 = 31526284
- 11 + 31526273 = 31526284
- 71 + 31526213 = 31526284
- 197 + 31526087 = 31526284
- 227 + 31526057 = 31526284
- 233 + 31526051 = 31526284
- 263 + 31526021 = 31526284
- 443 + 31525841 = 31526284
Showing the first eight; more decompositions exist.
