I don't think so

If you wrote it in a book, you could "retrieve" it from there.

If you could, what's the point of the passcode? Think about it.

Only solution is to put it in DFU mode and restore in iTunes, which will erase everything on the phone.

No, but you could reset it, by performing a Hard Reset and in case you want to gaining the best app for security, LEO Privacy Guard 3.0 would be the best.
