Earlier quoted context omitted.

It's hardly odd. "Even" just means "divisible by 2" "2 is the only prime that is divisible by 2" "3 is the only prime that is divisible by 3" "5 is the only prime that is divisible by 5" ... "N is the only prime that is divisible by N"

Exactly, we could also have a word for multiple of three or multiple of five

Threeven is used semi-seriously.

They are, by definition. The reason why we choose them is exactly to map a deductive framework onto an inductive reality.

That doesn’t seem to match the definition of “arbitrary”.

We can choose whichever axioms we want. There is still arguments over the axiom of choice, but nobody cares because it’s entirely helpful.
