Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526288, here are decompositions:
- 7 + 31526281 = 31526288
- 61 + 31526227 = 31526288
- 67 + 31526221 = 31526288
- 97 + 31526191 = 31526288
- 307 + 31525981 = 31526288
- 331 + 31525957 = 31526288
- 337 + 31525951 = 31526288
- 379 + 31525909 = 31526288
Showing the first eight; more decompositions exist.
