#include <stdio.h>

int main()
{
    int i, sum;
    int t;
    long int a[15];
    int n, count;
    for (sum = 6; sum < 500; sum++)
    {
        t = 0;
        n = 0;
        count = 0;
        for (i = 1; i < sum; i++)
        {
            if (sum%i == 0)
            {
                a[n] = i;
                t += a[n];
                n++;
                count++;
            }
        }
        if (sum == t)
        {
            printf("%d=", sum);
            for (n = 0; n < count; n++)
                printf("%d+", a[n]);

            printf("\n");
