I need to find or generate a very large Carmichael number (500 digits or longer). I've tried to find a database or just an example of such a number but failed. Is there any examples of really big Carmichael numbers or an implementation of an algorithm I'd be able to run locally?

Probably the best approach is to search a positive integer $k$, such that $6k+1$ , $12k+1$ , $18k+1$ are all prime. Then $$N=(6k+1)(12k+1)(18k+1)$$ is a Carmichael-number. If you find $k>10^{170}$ with the desired property , you are done.
