Digit fifth powers Problem 30 Project Euler

Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits:
1634 = 14 + 64 + 34 + 44
8208 = 84 + 24 + 04 + 84
9474 = 94 + 44 + 74 + 44
As 1 = 14 is not a sum it is not included.
The sum of these numbers is 1634 + 8208 + 9474 = 19316.
Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.
C CODE:
#include<stdio.h>
#include<limits.h>
main()
{
    int counter=0;
    int i;
    int sum=0;
    int result=0;
    for(i=10;i<=355000;i++)
    {
        int t=i;
        sum=0;
        while(t!=0)
        {
            sum=sum+pow(t%10,5);
            t=t/10;
        }
        if(sum==i){result=result+i;}
    }
printf("%d",result);

}
TIME TAKEN:

RESULT:
443839
