That's just how it is in 32-bit Emacs.
From the elisp manual:

  The range of values for integers in Emacs Lisp is -536870912 to
  536870911 (30 bits; i.e., -2**29 to 2**29 - 1) on typical 32-bit
  machines.

You can either use a 64-bit Emacs, or has been suggested, try
configuring --with-wide-int to get more range.
