Kolya is still trying to pass a test on Numbers Theory. The lecturer is so desperate about Kolya's knowledge that she gives him the same task every time. The problem is to check if $n!$ is divisible by $n^2$. \InputFile One integer $n~(1 \le n \le 10^9)$. \OutputFile Print "\textbf{YES}" if $n!$ is divisible by $n^2$, otherwise print "\textbf{NO}".
