Have:
'584323 Fri 13 May 2016 17:37:01 -0000 (UTC) 584324 Fri 13 May 2016 
13:44:40 -0400 584325 13 May 2016 17:45:25 GMT 584326 Fri 13 May 2016 
13:47:28 -0400'

Want:
[('584323', 'Fri 13 May 2016 17:37:01 -0000 (UTC)'),
   ('584324', 'Fri 13 May 2016 13:44:40 -0400'),
   ('584325', '13 May 2016 17:45:25 GMT'),
   ('584326', 'Fri 13 May 2016 13:47:28 -0400')]


Or maybe split() on space, then run through and add words of 6+ numbers 
to the list, then recombine everything until you hit the next group of 
6+ numbers, and so on?

The data is guaranteed to contain those 6+ groups of numbers.

Test with regexp under Python3

>>> import re
>>> s = '584323 Fri 13 May 2016 17:37:01 -0000 (UTC) 584324 Fri 13 May 2016 
13:44:40 -0400 584325 13 May 2016 17:45:25 GMT 584326 Fri 13 May 2016 
13:47:28 -0400'
>>> re.split("(\d{6})(.*?)", s)
['', '584323', '', ' Fri 13 May 2016 17:37:01 -0000 (UTC) ', '584324', '', ' 
Fri 13 May 2016 13:44:40 -0400 ', '584325', '', ' 13 May 2016 17:45:25 GMT 
', '584326', '', ' Fri 13 May 2016 13:47:28 -0400']


Dismiss empty items and strip whitespaces at begin or end of string, and 
that's done.

A+
Laurent.
Note: re experts will provide a cleaner solution.

  [m for m in re.findall(r'(\d{6}) (.*?) ?(?:(?=\d{6})|$)', s)]
