Two loops on archive page

I have 2 loops on the archive page. I want the first loop to display the 2 last posts of the category and the second loop offset 2 last post!

<div class="top-posts">
    <?php
    if (have_posts()) :
        while(have_posts()) : the_post();?>
            <div class="content">
                <?php the_post_thumbnail('archive'); ?>
                <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
            </div>
        <?php endwhile;?>
    <?php endif;?>
</div>

<div class="primary-posts">
    <?php
    if (have_posts()) :
        while(have_posts()) : the_post();?>
            <h2><a href="<?php the_permalink(); ?>" ><?php the_title(); ?></a></h2>
        <?php endwhile;?>
    <?php endif;?>
</div>
