Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531270, here are decompositions:
- 3 + 31531267 = 31531270
- 53 + 31531217 = 31531270
- 107 + 31531163 = 31531270
- 131 + 31531139 = 31531270
- 191 + 31531079 = 31531270
- 269 + 31531001 = 31531270
- 293 + 31530977 = 31531270
- 311 + 31530959 = 31531270
Showing the first eight; more decompositions exist.
