front page query_posts limit posts only on first page

Hello,

If answer for my question is somewhere, please link me solution. Do not know how search for it.

Problem is I would limit main page posts limit to 5. But when on page 2 and following, have default limit to 10. However, when I write it with is_paged() 5 posts (from first page) are missing.
Could I for example start from certain post number for use in is_paged()?

Why I would do it? Well, I am displaying slider and partners only on front page when ! is_paged(), so there is too much content with 10 posts.

Thanks in advance!
Greetings
