Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525344, here are decompositions:
- 13 + 31525331 = 31525344
- 61 + 31525283 = 31525344
- 83 + 31525261 = 31525344
- 101 + 31525243 = 31525344
- 131 + 31525213 = 31525344
- 167 + 31525177 = 31525344
- 181 + 31525163 = 31525344
- 223 + 31525121 = 31525344
Showing the first eight; more decompositions exist.
