zby,
No, the riddle would be more like:

Produce a prime number whose sum when added to itself is the same as the product if multiplied by itself.

The point is that until you know the answer is 2 + 2 = 4 = 2 * 2, you can't write a program that prints out 4. The challenge is not to figure out the solution and then write a translation of that solution into the program. The challenge is to write a program that given the rules can figure out a solution (since there may be more than one).

If it is still not clear and you need another example, see Challenge: Setting Sun Puzzle.

Cheers - L~R
