How do you index any location of a program whose size is bigger than the virtual memory?

Question

Virtual memory is something that can be indexed by CPU alone, a 32 bit architecture is capable of generating 2^32 locations(say byte addressable machine then 2^32 bytes=4GB). Surely we can use demand paging if process size is bigger than RAM, but what if the process size is bigger than virtual memory itself ? Surely, you can again use demand paging, but my question is, how can CPU locate any bytes greater than 2^32 ? Say program is written has size of 5GB, how does cpu index the bytes greater than 5GB ? It can only generate locations till 4GB.
