#include<bits/stdc++.h>
using namespace std;
int n;
int main(){
	cin>>n;
	if(n%2==0&&n!=2)cout<<"YES";
	else cout<<"NO"; 
	return 0;
}

#include<bits/stdc++.h>
using namespace std;
int n;
int main()
{
    cin>>n;
    if(n%2==0&&n>3)
    {
        cout<<"YES"<<endl;
    }
    else
    {
        cout<<"NO"<<endl;
    }
    return 0;
}

极度简单，同学们仔细算一算，只要是偶数分两部分就是偶数，但2分出0和2，题目中说不能为0，所所以必须特判。

#include<bits/stdc++.h>
using namespace std;
int x;
int main(){
	cin>>x;
	if(x%2==0&&x!=2) cout<<"YES";
	else cout<<"NO";
	return 0;
}

#include<bits/stdc++.h>
using namespace std;
long n;
int main()
{
	cin>>n;
	if(n%2||n<5)cout<<"NO";
	else cout<<"YES";
	return 0;
}

#include<bits/stdc++.h> using namespace std; long long n; int main() { cin>>n; if(n2)cout<<"NO"; else if(n%20)cout<<"YES"; else cout<<"NO"; return 0; }

#include<bits/stdc++.h>
using namespace std;
long long n;
int main(){
cin>>n;
if(n%2==0&&n>4) cout<<"YES";
else cout<<"NO";
return 0;
}
