Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471630, here are decompositions:
- 53 + 31471577 = 31471630
- 107 + 31471523 = 31471630
- 149 + 31471481 = 31471630
- 173 + 31471457 = 31471630
- 191 + 31471439 = 31471630
- 233 + 31471397 = 31471630
- 257 + 31471373 = 31471630
- 269 + 31471361 = 31471630
Showing the first eight; more decompositions exist.
