The largest prime number known is 2^57,885,161 − 1. How do we know that this number is prime?

Were computers involved in the calculation? And if so, how can computers calculate past their [current] maximum values of 2^64?

That isn't the current maximum value for computers. It's (one past) the maximum value of a 64-bit unsigned integer, which is the natural (fastest/most convenient) way to store integers on modern consumer general-purpose computers (i.e., the general purpose registers on x86-64 CPUs are 64 bits). But a program may combine several such integers into an aggregate data structure that can represent arbitrarily-large numbers (up to addressable memory limitations).
