I'm afraid it is the maximum possible number…

See Section 6 of RFC 3977:

    Article numbers MUST lie between 1 and 2,147,483,647, inclusive.  The
    client and server MAY use leading zeroes in specifying article
    numbers but MUST NOT use more than 16 digits.  In some situations,
    the value zero replaces an article number to show some special

    Note that it is likely that the article number limit of 2,147,483,647
    will be increased by a future revision or extension to this
    specification.  While servers MUST NOT send article numbers greater
    than this current limit, client and server developers are advised to
    use internal structures and datatypes capable of handling larger
    values in anticipation of such a change.

The protocol does not define (yet) a way to use higher numbers for 
numbering articles.
INN does not handle that, and I do not think it will be implemented 
soon.  We first need to specify how the extension to the protocol should 
be dealt with.

Meanwhile, the only solution I see for your problem is to renumber the 
newsgroups to start from 1.  I know there are drawbacks for readers but 
we do not have any other solution with INN.
(Ray already did that with eternal-september.  Maybe he could give you 
some tips if you wish to do the same thing.)
