Well.. We could set up an organized network where if you sign up, you will be assigned some numbers to play, and you'll take home a part of the prize, guaranteed. Your share is in proportion to your investment.
That way, you don't need 292m to take the prize, and any average Joe can decide to invest, say $100, and still come out positive.
Of course, it can very well become an organizational nightmare :-)
