描述：

One hot summer day Pete and his friend Billy decided to buy a watermelon. They chose the biggest and the ripest one, in their opinion. After that the watermelon was weighed, and the scales showed w kilos. They rushed home, dying of thirst, and decided to divide the berry, however they faced a hard problem.

在一个很炎热的夏天Pete和他的好朋友Billy决定买一个西瓜。他们选择了他们认为的最大和最成熟的西瓜。在称过那个西瓜之后，重w千克，他们跑回家，感觉很渴，决定分瓜吃，但是他们面临一个严峻的问题。

Pete and Billy are great fans of even numbers, that's why they want to divide the watermelon in such a way that each of the two parts weighs even number of kilos, at the same time it is not obligatory that the parts are equal. The boys are extremely tired and want to start their meal as soon as possible, that's why you should help them and find out, if they can divide the watermelon in the way they want. For sure, each of them should get a part of positive weight.

Pete和Billy是偶数的狂热爱好者，这也是为什么他们想把西瓜分成两部分且都是偶数重量，同时不强制要求这两部分是同等重量。他们非常累想尽可能快的开始吃西瓜，这就是为什么你要帮助他们，他们是否能将西瓜分成他们想要的样子，当然，他们每一个人都应该得到一部分正数质量的西瓜。

输入：

The first (and the only) input line contains integer number w (1 ≤ w ≤ 100) — the weight of the watermelon bought by the boys.

第一个（也是唯一一个）输入的整数是w（1<=w<=100)——他们买的西瓜的质量。

输出：

Print YES, if the boys can divide the watermelon into two parts, each of them weighing even number of kilos; and NO in the opposite case.

输入YES，如果他们可以将西瓜分成两部分，每一部分重量为偶数；反之，输出NO。

样例输入：

8

样例输出：

YES

注释：

For example, the boys can divide the watermelon into two parts of 2 and 6 kilos respectively (another variant — two parts of 4 and 4 kilos).

例如，他们可以将西瓜分成分别为2kg和6kg（另一种情况——2部分都是4kg）。
