要注意：a和b都要是偶数！

#include<bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cin >> n;

    int a=n/2,b=n/2;
    if(n==0){
        cout << "NO";
    }
    else if(n/2*2==n){
        if(a%2==0 && b%2==0){
            cout << "YES";
        }else cout << "NO";
    }else cout << "NO";
    return 0;
}
