Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594270, here are decompositions:
- 23 + 31594247 = 31594270
- 107 + 31594163 = 31594270
- 137 + 31594133 = 31594270
- 173 + 31594097 = 31594270
- 311 + 31593959 = 31594270
- 317 + 31593953 = 31594270
- 401 + 31593869 = 31594270
- 431 + 31593839 = 31594270
Showing the first eight; more decompositions exist.
