query if on page/2/?

hey guys,
is there a way to check if i’m currently not on the frontpage of my blog?
I know there are conditional tags like is_home(). However that won’t work if I’m on myblog.com/page/2/

I have a pagination on my frontpage that let’s users jump to the next page. If I’m on the second page i want to show a “Back Home” link.

any idea how I could achieve that?

thank you.
