You could do the same thing you've been doing to recover the wallet on Electrum or maybe Bitaddress[1] (download the source code first), you should just make sure that the device you're using is offline and safe.

For peace of mind, I (would) do this every time when I create any offline wallet (before funding it). It doesn't hurt to make sure you can recover your backups.

Ok, so if I get it right, you mean I should re-run my own code, to see whether the private key generates the address. And, I must do it offline. Correct?

There are different ways of doing it.

1) Since you've already sent the small amount of Bitcoins, you can create a transaction that spend a small amount of Bitcoin to your address. You can spend a fraction of that with a small fee, the confirmation doesn't matter. So long as you can see the transaction on blockexplorer, it's fine.

2) Sign a message with the address. If you can verify it, then it would be fine.

3) Import it into an offline wallet. So long as the wallet allows it to be imported, it should be valid and its perfectly safe. Which is what you've done. Well-known and working wallet have sanity checks on your private key which prevents those which aren't working to be imported.

Thanks for the options. The second one seems somewhat sophisticated. I ll check it out, but it looks tricky to do it totally offline, since I don't know which tools I must use.
