How do I unzip a zip - file that Numbers says is too big at 129mb?

OK. This is the OFFSHORE BANKING LEAK from the ICIJ that I have been waiting for for almost five years and after I download it from the ICIJ site and go to open it, iWork>Numbers says it's too big. I believe that 129mb is the zipped volume. I am clueless. Can anyone help to open this file?
