Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536230, here are decompositions:
- 3 + 31536227 = 31536230
- 7 + 31536223 = 31536230
- 43 + 31536187 = 31536230
- 181 + 31536049 = 31536230
- 211 + 31536019 = 31536230
- 283 + 31535947 = 31536230
- 409 + 31535821 = 31536230
- 421 + 31535809 = 31536230
Showing the first eight; more decompositions exist.
