java if condition never executes with or operation

why does this piece of code always enters the if condition no matter what the input is?

 Scanner input = new Scanner(System.in);
    int x = input.nextInt();
    if (x != 4|| x!= 3)
        System.out.println("testing");

The problem is definately with the NOT combined with OR because if instead of != i write == it works (obviously different logic than what i want but still works).
