Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536210, here are decompositions:
- 7 + 31536203 = 31536210
- 23 + 31536187 = 31536210
- 109 + 31536101 = 31536210
- 113 + 31536097 = 31536210
- 149 + 31536061 = 31536210
- 157 + 31536053 = 31536210
- 191 + 31536019 = 31536210
- 193 + 31536017 = 31536210
Showing the first eight; more decompositions exist.
