Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525600, here are decompositions:
- 11 + 31525589 = 31525600
- 47 + 31525553 = 31525600
- 101 + 31525499 = 31525600
- 179 + 31525421 = 31525600
- 233 + 31525367 = 31525600
- 257 + 31525343 = 31525600
- 269 + 31525331 = 31525600
- 311 + 31525289 = 31525600
Showing the first eight; more decompositions exist.
