Programming Challenge: Find a Particular Prime Number

[Thomas Okken]

If you want to exclude Billiarde and Billion (or if you want to exclude all solutions that consist of multiple words) then the answer is 808853.

I'm not surprised that people in Vienna don't read a 13-digit number as something containing the word "Billion." I read German-language news every day, and the word Billion shows up very rarely. Millionen and Milliarden, yes, but Billionen, not so much.
