Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526312, here are decompositions:
- 31 + 31526281 = 31526312
- 73 + 31526239 = 31526312
- 229 + 31526083 = 31526312
- 331 + 31525981 = 31526312
- 409 + 31525903 = 31526312
- 421 + 31525891 = 31526312
- 463 + 31525849 = 31526312
- 541 + 31525771 = 31526312
Showing the first eight; more decompositions exist.
