You asked this while I was at work, so I don't have access to my spreadsheet of prime numbers. I wrote a program that generates prime numbers, but I have only the first 65,536 of them--I don't have the macro configured to start a new column.
I also looked at even larger prime numbers made by multiplying prime numbers and then adding 1--sometimes the result is prime and sometimes it isn't.
How many digits would you like in the prime number?
I think the current record for "largest known prime" is in the thousands of digits.
edit: Ah so--it looks like the largest ones are into the *millions* of digits.

On the page whose link is given below, there are 95 prime numbers of 210 to 300 digits. There are examples of smaller prime numbers on the two previous pages .../small2.html and .../small1.html.
With modern computers and algorithms, it is no trouble at all to generate and verify prime numbers up to 500 or 600 digits.
