Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529300, here are decompositions:
- 31 + 31529269 = 31529300
- 43 + 31529257 = 31529300
- 151 + 31529149 = 31529300
- 193 + 31529107 = 31529300
- 211 + 31529089 = 31529300
- 307 + 31528993 = 31529300
- 331 + 31528969 = 31529300
- 457 + 31528843 = 31529300
Showing the first eight; more decompositions exist.
