print a __m128i variable

I'm trying to learn to code using intrinsics and below is a code which does addition

compiler used: icc

#include<stdio.h>
#include<emmintrin.h>
int main()
{
        __m128i a = _mm_set_epi32(1,2,3,4);
        __m128i b = _mm_set_epi32(1,2,3,4);
        __m128i c;
        c = _mm_add_epi32(a,b);
        printf("%d\n",c[2]);
        return 0;
}

I get the below error:

test.c(9): error: expression must have pointer-to-object type
        printf("%d\n",c[2]);

How do I print the values in the variable c which is of type __m128i
