Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525032, here are decompositions:
- 5 + 31525027 = 31525032
- 41 + 31524991 = 31525032
- 43 + 31524989 = 31525032
- 139 + 31524893 = 31525032
- 193 + 31524839 = 31525032
- 223 + 31524809 = 31525032
- 239 + 31524793 = 31525032
- 241 + 31524791 = 31525032
Showing the first eight; more decompositions exist.
