A structually self-supporting hollow Earth?

Is it possible to have a structurally self-supporting hollow Earth where the weight of the shell is balanced against the atmospheric pressure inside?

• It must be human habitable (gravity is nice but optional)
• It must be able to keep its occupants safe from radiation from space....
• It must be able to survive a long long time floating around the solar system without becoming uninhabitable.
• The designers couldn't afford to use hand-wavium so they had to make do with more traditional construction materials (which, thankfully were not in short supply)

Is such a structure actually possible, and if so, how big can it get before it isn't?
