I disagree. Had the number some actual reason for being chosen, some relevance, or some greater purpose, then such would have come out in the book. As it stands, the complete and utter irrelevance of it is almost a plot point in the book. That there is a great system of machinations far greater than what any single individual could possibly understand is a fantastic premise -- that it derives a nonsensical answer that the universe can't comprehend is even more fantastical, and in my opinion, is part of what works about the story; I honestly don't think it would have held as well if the number actually had some importance.
