Wittgenstein didn’t think that everything was a command or request; his point was that making factual claims about the world is just one particular use of language that some philosophers (including early Wittgenstein) had hyper-focused on.
Anyway, his claim wasn’t that “five” was nonsense, just that when we understood how five was used there was nothing further for us to learn. I don’t know if he’d even say that the abstract concept five was nonsense, he might just say that any talk about the abstract concept would inevitably be nonsense or unjustified metaphysical speculation.
These are situations where I woud like to give a specific question to the philosopher. In this case it would be: “Is being a prime number a property of number five, or is it just that we decided to use it as a prime number?”
I honestly have no idea how he’d answer, but here’s one guess. Maybe we could tie prime numbers to one of a number of processes for determining primeness. We could observe that those processes always return true for 5, so in a sense primeness is a property of five.
