What is the purpose of decomposing a Tuple?

Can someone name some practical applications when you would want to use a Tuple and when would you want to decompose a Tuple? Not quite getting the value of a Tuple in the real world.

I see it like the HTTP codes, where you have a codeError (404) and a codeMessage (Page not found). This could be an interisting approach to develope an exception's handling system. Don't you think? For the decomposition, it's only a practical way to acces the variables; it lets the code be more readable (as naming the parameters).
