I want to remove older updates from APP Store update page that will not install because they are not compatable with my OS Version 10.8.5

There are a couple of updates on my APP STORE page that are extremely annoying, they can't be installed because they are to old for my OSX version 10.8.5, I want to delete or remove them so that Spotlight stops telling me that I have 2 updates to install, when they can't be installed unless I revert to an older OS version.
