Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531192, here are decompositions:
- 29 + 31531163 = 31531192
- 53 + 31531139 = 31531192
- 113 + 31531079 = 31531192
- 191 + 31531001 = 31531192
- 233 + 31530959 = 31531192
- 359 + 31530833 = 31531192
- 419 + 31530773 = 31531192
- 479 + 31530713 = 31531192
Showing the first eight; more decompositions exist.
