Error404 personalised pages in multilingual site

Question

For SEO I need personalised error404 pages for all languages in my multilingual site. I have added the following code to error.php in the template map:

$lang = JFactory::getLanguage();

$result = $lang->getTag();

if (($this->error->getCode()) == '404') {

  if ($result=="nl-NL") {
      header('Location: /index.php?option=com_content&view=article&id=3415');
      exit;
  }
  if ($result=="en-GB") {
      header('Location: /index.php?option=com_content&view=article&id=3415');
      exit;
  }

However only the default language gives the right result. Please tell me what to change
