Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531630, here are decompositions:
- 3 + 31531627 = 31531630
- 107 + 31531523 = 31531630
- 173 + 31531457 = 31531630
- 227 + 31531403 = 31531630
- 359 + 31531271 = 31531630
- 467 + 31531163 = 31531630
- 491 + 31531139 = 31531630
- 653 + 31530977 = 31531630
Showing the first eight; more decompositions exist.
