Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525810, here are decompositions:
- 11 + 31525799 = 31525810
- 23 + 31525787 = 31525810
- 47 + 31525763 = 31525810
- 257 + 31525553 = 31525810
- 311 + 31525499 = 31525810
- 389 + 31525421 = 31525810
- 431 + 31525379 = 31525810
- 443 + 31525367 = 31525810
Showing the first eight; more decompositions exist.
