Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525762, here are decompositions:
- 113 + 31525649 = 31525762
- 173 + 31525589 = 31525762
- 263 + 31525499 = 31525762
- 383 + 31525379 = 31525762
- 419 + 31525343 = 31525762
- 431 + 31525331 = 31525762
- 479 + 31525283 = 31525762
- 599 + 31525163 = 31525762
Showing the first eight; more decompositions exist.
