Use a product like Observepoint to search your site and see what it finds.
Or your CMS should have some way to know what pages are out there and you can make sure they all have the common footer that contains your tags etc.
There is no way with Adobe Analytics since by definition it doesn't know a page exists unless there is s_code (et al) on the page to trigger analytics. Even your 404 error page needs to have s_code on it to tell you what 404 error it is.
