Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525750, here are decompositions:
- 101 + 31525649 = 31525750
- 149 + 31525601 = 31525750
- 197 + 31525553 = 31525750
- 251 + 31525499 = 31525750
- 353 + 31525397 = 31525750
- 383 + 31525367 = 31525750
- 419 + 31525331 = 31525750
- 461 + 31525289 = 31525750
Showing the first eight; more decompositions exist.
