Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525200, here are decompositions:
- 17 + 31525183 = 31525200
- 23 + 31525177 = 31525200
- 37 + 31525163 = 31525200
- 73 + 31525127 = 31525200
- 79 + 31525121 = 31525200
- 97 + 31525103 = 31525200
- 163 + 31525037 = 31525200
- 173 + 31525027 = 31525200
Showing the first eight; more decompositions exist.
