Cool! Like you, it figured out quickly that "acht Billiarden" must be the starting point.

Next, I came to the conclusion that I only have very few calculators in my collection which might me capable of testing if such large integers are primes, converting the numbers to strings and storing and sorting those strings. And all in a survivable timespan... The Hp50, Ti89/200, HP71B and a couple of other BASIC programmables maybe.

Looking forward to see some actual programs running on a calculator!
