Multithreads running the same function in parallel

Question

I’m trying to get this code to run the function calculaPrimo() on each thread in parallel to find prime numbers in a range of 1 up to the maximum value passed via command line, for example if the user put the maximum value as 100 and the number of maximal threads as 2 I wanted to make thread 1 analyze the numbers: 1,3,5... and thread 2 the numbers:2,4,6... but what is happening is that each thread is going through the interval again resulting in that output:

follows the code below:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *calculaPrimo(void *limitValue) {
    int primo, j;
    int num = 1;
    int maxValue = *(int*)limitValue;

    while (num <= maxValue) {
        primo = 1;

        for (j = 2; j < num && primo; j++) {
            if (num % j == 0) {
                primo = 0;
            }
        }
        if (primo == 1) {
            printf("%d ", num);
        }
        num++;
    }
    printf("\n");

    return NULL;
}

void criaThreads(char* const* args) {
    int maxValue;
    int maxThreads;
    long t;
    pthread_t *threads;

    maxValue = atoi(args[1]);
    maxThreads = atoi(args[2]);

    printf("Maximum integer   %d\n", maxValue);
    printf("Number of threads %d\n", maxThreads);
    
    threads = (pthread_t *)calloc(sizeof(pthread_t), maxThreads);

    for (t = 0; t < maxThreads; t++) {
        pthread_create(&threads[t], NULL, calculaPrimo, &maxValue);
    }

    for (t = 0; t < maxThreads; t++) {
        pthread_join(threads[t],NULL);
    }
}


int main(int argc, char* const* argv) {
    if (argc < 3) {
        printf("%s: insufficient parameters. Please inform maximum value and number of threads\n", argv[0]);
        return 1;
    }

    criaThreads(argv);
    pthread_exit(NULL);
    return 0;
}
