how to find twin prime less than 100 in R using, loop and cat

Firstly, this sounds like a homework assignment, so do be aware of our homework policy, FAQ: Homework Policy

This kind of thing is pretty straightforward to do with R. Assuming this a homework question, could you let us know what you've attempted to do already, what issues you're having? Ideally, pose these with a reprex.

Also, I am not familiar with or cat prime, in either base-R or an R package on CRAN after a quick search. Could you set these up?
