Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525632, here are decompositions:
- 23 + 31525609 = 31525632
- 29 + 31525603 = 31525632
- 31 + 31525601 = 31525632
- 43 + 31525589 = 31525632
- 79 + 31525553 = 31525632
- 211 + 31525421 = 31525632
- 349 + 31525283 = 31525632
- 353 + 31525279 = 31525632
Showing the first eight; more decompositions exist.
