Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526512, here are decompositions:
- 23 + 31526489 = 31526512
- 89 + 31526423 = 31526512
- 239 + 31526273 = 31526512
- 443 + 31526069 = 31526512
- 449 + 31526063 = 31526512
- 461 + 31526051 = 31526512
- 491 + 31526021 = 31526512
- 593 + 31525919 = 31526512
Showing the first eight; more decompositions exist.
