There are 90 palindromic numbers between 100 and 1000
The sum of all palindromic numbers from 1001 to 9999 is 495000.
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.

No.
No. For instance, 101 is not divisible by 11.
Nobody went out to create them: some numbers simply happen to be palindromic and others don't.
