C :

#include<stdio.h>

void main(){
    int i,n;
    scanf("%d",&n);

    for(i=0;i<=n/2;i++){
        printf("%d=%d+%d\n",n,i,n-i);
    }
}

C++ :

#include <bits/stdc++.h>
using namespace std;
 
int main(){
    int n;
    cin>>n;
    for(int i = 0;i <= n / 2;i++){
   		cout<<n<<"="<<i<<"+"<<(n-i)<<endl;  
    }
}

Java :

import java.util.*;
public class Main{
	public static void main(String args[]){
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		for(int i = 0;i<=n/2;i++){
			System.out.println(n+"="+i+"+"+(n-i));
		}
	}
}

Python :

n=int(input())
a=0
b=n//2
for a in range(n//2+1):
    for b in range(n//2,n+1):
        if a+b==n:
            print('{}={}+{}'.format(n,a,b))
