there is no editor capable in opening such large files
Sure there is. Emacs can do it (I just tried it). It's quite slow, but it works. And even if it didn't work, core commands like 'diff' shouldn't arbitrarily limit themselves to small files.
No doubt 'diff' can be fixed to work even on MS-Windows platforms. However, arbitrarily limiting line numbers to 32 bits is not the way to go about it.
