Remove laravel 5 and install laravel 4

I was about to install laravel 4 but accidentally installed laravel 5 instead, now I need to remove 5 and install 4, I tried to change in the composer the line that says: require: "laravel/framework": "5.1.", and overwrite it by "laravel/framework": "4.2.", but when I create a new project it still creates it in laravel 5 unless I point to version 4 with the creation command, any help?
