CF4A.Watermelon

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.

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.

一个炎热的夏日，皮特和他的朋友比利决定买一个西瓜。在他们看来，他们挑选了最大、最熟的一个。随后，这个西瓜被称重，电子秤显示其重量为 $w$ 千克。他们急急忙忙赶回家，渴得不行，于是决定将这个西瓜分而食之；然而，他们却面临一个难题。

皮特和比利都非常喜欢偶数，因此他们希望将西瓜分成两部分，使得每一部分的重量（单位：千克）均为偶数。注意：这两部分的重量不必相等。两个男孩已经疲惫不堪，希望能尽快开始享用，因此你需要帮他们判断：是否能够按他们所期望的方式切分西瓜？当然，每人分得的部分重量必须为正数。

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

第一行（也是唯一一行）输入包含一个整数 $ w $（$ 1 \leq w \leq 100 $）——表示男孩们购买的西瓜的重量。

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.

如果两个男孩能将西瓜分成两部分，且每部分的重量均为偶数千克，则输出 YES；否则输出 NO。

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，男孩们可以将西瓜分成两部分，分别为 2 千克和 6 千克（另一种方案是分成两个均为 4 千克的部分）。
