The .numbers file is actually a directory.  There should be an image 

file.numbers/QuickLook/Thumbnail.jpg


that contains a preview of the document.  It might contain the information that you are looking for.  The contents on the file are actually stored in a compressed xml file

file.numbers/index.xml.gz


If you are just looking for some bit of information, you might be able to find it in there.  For the most part, unless you have something to parse the xml, it would take quite a bit of work to reconstruct the spreadsheet from the xml.
