Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525186, here are decompositions:
- 3 + 31525183 = 31525186
- 23 + 31525163 = 31525186
- 59 + 31525127 = 31525186
- 83 + 31525103 = 31525186
- 149 + 31525037 = 31525186
- 179 + 31525007 = 31525186
- 197 + 31524989 = 31525186
- 293 + 31524893 = 31525186
Showing the first eight; more decompositions exist.
