PI is not copyrighted, because that would be silly, but if you were to find the exact bytes in there to reproduce the next Marvel movie and you started sharing that offset, that would probably be copyright infringement. The fact that neither of those numbers were part of the original work, or copyrightable in isolation, or that "technically everything is present in pi", is immaterial. It's obvious to any non-pedantic human being that you're infringing on the creative work.
