How to check integrity of public & private key pairs?

[samadamsbeer]

If I get public and private key pairs, that I have never used before, is there a way to check their integrity without spending the Bitcoins? I'd hate to think I have a good paper wallet stored somewhere but then find out there was some computer glitch, typo I made writing them down, or printer issue that screws up an address and makes the BTC no longer spendable. It'd be nice if there was a way to check these pairs are good, entirely offline.
