But by the same reasoning, we have no reason to think they are anything
but non-irreducible (reducible, I guess). What the heck does it mean
for a natural number to be irreducible anyway? I know what it means for
a polynomial to be irreducable, but the natural number analogy would be
a composite number, and there are plenty of those.
