Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625022, here are decompositions:
- 43 + 31624979 = 31625022
- 71 + 31624951 = 31625022
- 83 + 31624939 = 31625022
- 101 + 31624921 = 31625022
- 173 + 31624849 = 31625022
- 193 + 31624829 = 31625022
- 223 + 31624799 = 31625022
- 239 + 31624783 = 31625022
Showing the first eight; more decompositions exist.
