Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594198, here are decompositions:
- 5 + 31594193 = 31594198
- 47 + 31594151 = 31594198
- 101 + 31594097 = 31594198
- 137 + 31594061 = 31594198
- 149 + 31594049 = 31594198
- 239 + 31593959 = 31594198
- 359 + 31593839 = 31594198
- 401 + 31593797 = 31594198
Showing the first eight; more decompositions exist.
