17717. Oooh! There's a cool number there. All digits are prime numbers, as are all but one combination of any two: 11, 17 and 71 (not 77, though) and no combinations of any three are prime. Maybe not such a big deal, but fun when you try to look for things like that.

17719. My friends and I once tried to figure out the largest prime number.

We weren't even close: 2[SUP]43,112,609[/SUP]-1, and that's only the largest found so far. It contains 13 million digits if written out longhand. It would be 30 miles long if printed in 12-point font.
