Why is it necessary that 2+2=4?

Why is it necessary that 2+2=4? Because it is difficult to conceive how 2+2 could have been other than 4? But how do we know that this is not just due to our limitations? The fact that we, i.e. our brains, cannot imagine a different result does not per se mean that it is logically impossible for 2+2 not to be 4 (given the standard semantics of course).
