Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525700, here are decompositions:
- 13 + 31525687 = 31525700
- 43 + 31525657 = 31525700
- 97 + 31525603 = 31525700
- 163 + 31525537 = 31525700
- 211 + 31525489 = 31525700
- 223 + 31525477 = 31525700
- 421 + 31525279 = 31525700
- 433 + 31525267 = 31525700
Showing the first eight; more decompositions exist.
