\begin{proof} 
We cross out all propers multiples of $3,5,7,11,13$ ($17^2 > 200$). We obtain
\begin{align*}
&2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97,\
 &101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199.
\end{align*}
\end{proof}
