CodeForces - 4A

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.

Input

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

Output

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.

Examples

Input

8

Output

YES

Note

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).

程式分析：只需西瓜的斤數為2的倍數且不為二即可滿足所有條件。

#include<stdio.h>

int main()
{
	int w;
	scanf("%d",&w);
	if(w<1||w>100) return 0;
	if(w%2==0&&w>2)
	{
		printf("YES");
	}
	else printf("NO");
	return 0;
}
