title: Vim: split line at the end of 4 random number sequences
body: <p>I have a text file that is all contained in one line. </p>
  
  <p>e.g.</p>
  
  <pre><code>Scheme 4078 6291 4205 66 Video 23522 4323 53522 4233 Social 23 5432 6 54
  </code></pre>
  
  <p>I would like to split it up into lines that keep the name and its four assocated numbers on one line.</p>
  
  <p>hence:</p>
  
  <pre><code>Scheme 4078 6291 4205 66
  
  Video 23522 4323 53522 4233 
  
  Social 23 5432 6 54
  </code></pre>
  
  <p>I've been trying things like</p>
  
  <pre><code>/[[:digit:]]+ [[:digit:]]+ [[:digit:]]+ [[:digit:]]+ 
  </code></pre>
  
  <p>And I figure that it must go into a line that involves :%s but I'm getting lost. 
  Any help?</p>
