Yes, and in the same way

b^p = b + py
and
c^p = c + pz.

Up to now you  may assume
a^p + b^p = c^p
where p is a prime >= 2
and 0 <  a <= b < c,
a, b, c integers.

You correctly conclude in (1) that
a + b - c > 0.

Further by Fermat's  little theorem
p (z-x-y) = a + b - c.

Therefore
z-x-y >= 1 and thus
a > a + b - c >= p.

So it seems to me that you also disprove the case p = 2.
