Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536258, here are decompositions:
- 31 + 31536227 = 31536258
- 71 + 31536187 = 31536258
- 97 + 31536161 = 31536258
- 157 + 31536101 = 31536258
- 197 + 31536061 = 31536258
- 239 + 31536019 = 31536258
- 241 + 31536017 = 31536258
- 277 + 31535981 = 31536258
Showing the first eight; more decompositions exist.
