Congrats! (for the youngest...)
However, I don't think we should encourage this, i.e. posting tiny primes, unless they have a very special significance. Otherwise we will end up like factorDB, flooded with random primes below 50 digits, by some "cmd" guy.

Even your post, is excessively long and the most of the list is futile, you should use "code" tags for such posts in the future.
