This has already been suggested, but you could always create a double spend of your inputs...
1) export your private key*
2) download coinb.in sourcecode*, put it on a usb-stick
3) on an online computer, open the index.html from coinb.in on your usb-stick
4) click on new-> transaction
5) fill in the address "1GAzLcKNdTaNPHc4oVG2EuxNFciASNUZ8r" and click "load"
6) since you only have 2 inputs, and you need both, you don't have to mess with the inputs...
7) create 2 outputs => one to 1Fh3km4GUMYhAqqchNLdcxYGu7R6wBZqnX (4BTC) and one to 1GAzLcKNdTaNPHc4oVG2EuxNFciASNUZ8r with the change... Make sure you don't send everything back to yourself, all the "leftover" coins will be used as a fee. Make sure you calculate your fee correctly!!!!
click on submit
9) copy the transaction, put it in an ascii-file and save it on your usb-stick
10) reboot your pc, preferably using a linux livecd* WITHOUT internet connection
11) insert the usb-stick, open index.html
12) click on sign, copy your private key from step 1 in the private key box, copy your transaction from step 9 in the big box, click on submit
13) now you'll see a hex encoded bitcoin transaction, copy it, paste it in an ascii-file on your usb-stick
14) reboot your pc again, now in your "normal" os, with internet connection, open index.html again
15) click on broadcast, paste the hex encoded bitcoin transaction from step 13 in the box, and click broadcast
you have now created a double spend
There are many other ways of doing this... But i think this is the easyest one
Edit:
1a) open your blockchain wallet
1b) click on import/export
1c) click on "i understand"
1d) the easyest is clicking on "paper wallet"
1e) re-enter your password
1f) you'll now see a paper wallet, showing your private and public keys
2a)
