Put $g=y^2-zw$. Every generator of $I$ is divisible by $x^2$ and belongs to $(y,z)^2$, while the displayed decomposition in the next part will show that
$$
\sqrt I=(x)\cap(y,z).
$$
Its two minimal primes, and hence its isolated associated primes, are
$$
\boxed{\mathfrak p_1=(x),
\qquad \mathfrak p_2=(y,z).}
$$
The corresponding isolated primary components are
$$
\boxed{\mathfrak q_1=(x^2),
\qquad \mathfrak q_2=(y,z)^2=(y^2,yz,z^2).}
$$
