Thank you for the research and effort to share these results.

I am frequently amazed and impressed with the enormous amounts of resources and effort folks dedicate to researching Primes, and meta-data about Primes, with no clear predetermined benefit of doing so. Not complaining, just curious why so many people are drawn to research in this area, and what goals they set pursuing such research.

Have any significant non-academic-only results come about as a result of Prime research that isn't well-known, or maybe widely-known, but apparently not by me?
