How to set different application template for 404 page?

Site has traditional template structure elements: header, content, footer. And almost all pages of the site has such structure. But 404-page doesn't have the header.

So my question is: Is there some clean way to set unique application template for 404-page?

Of course I can add {{ partial 'header' }} to the begining of all templates, beside 404-page, but I hope there is right way to do this ...

Thanx

P.S. Sorry for my English
