Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536250, here are decompositions:
- 23 + 31536227 = 31536250
- 47 + 31536203 = 31536250
- 89 + 31536161 = 31536250
- 149 + 31536101 = 31536250
- 197 + 31536053 = 31536250
- 233 + 31536017 = 31536250
- 269 + 31535981 = 31536250
- 311 + 31535939 = 31536250
Showing the first eight; more decompositions exist.
