Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536326, here are decompositions:
- 13 + 31536313 = 31536326
- 103 + 31536223 = 31536326
- 139 + 31536187 = 31536326
- 229 + 31536097 = 31536326
- 277 + 31536049 = 31536326
- 307 + 31536019 = 31536326
- 379 + 31535947 = 31536326
- 499 + 31535827 = 31536326
Showing the first eight; more decompositions exist.
