Long prime list - filter version - 26 entries

I've used the maximum input/diff/output size allowed by vimgolf to get a list of integers up to 1460 separated by newlines, and your goal is to only keep the lines containing primes. There are 232 of them I hope some of you will golf vimscript itself to create some function to run as a primality check for each line, which is a good exercise if you haven't done much vimscript yet! You're invited to also try copy-pasting and doing other non-smart text manipulation. Even more interesting would be to see a solution that uses text manipulation to do the filtering! Whether you use vimscript, normal-mode primality checks, or text manipulation, as long as the end result is valid, your answer will be valid! Let's see which method does better here. Best of luck!
