Can you break up the following number into groups of smaller numbers, without changing the order of the figures, so that the SUM of all the groups is equal to the square of the first group?

123 456 789. Thanks for help.

OK, how about this arrangement:

12 + 34 + 5 + 6 + 78 + 9 = 144 !!. I think it meets the conditions! 123 + others will NOT work, because 123^2 =15,129. All the other numbers will never add up to 15,129!.
