Is (2^285039757)-1 prime?

I plugged this number into Wolfram Alpha and it says "unknown". Did I find a new prime number or am I just stupid?

Edit: It is decidedly not prime

A prime number is a number that has only two positive factors that being 1 and X the number itself. That means a prime number can't be evenly divided by another whole number other than those two factors.

3 and 5 are prime numbers since they can only be divided by 1 and 3 in the case of 3 and 1 and 5 in the case of 5.

6 isn't a prime number since it can be divided by 1, 2, 3, and 6.

In the case of 1 it isn't a prime since it only has one factor hope this helps you.
