502896 already that many coins....!

999/dif^2

is going to run out of coins soon

Note that in Primecoin difficulty increases exponentially. If a difficulty of 8 is, say, 30 times the difficulty of 7, then a difficulty of 9 is 30 times the difficulty of 8. To get to a block reward of 10 we would need a difficulty of 10, which is hundreds of times the difficulty we have today. To get to 5 we would need a difficulty of 14, which would mean we were generating primes worthy of the current record books about every minute. If we got to a difficulty of 17--the longest known Cunningham chain right now--we would still have about 3.5 XPM per block. Rewards are certainly going down, but decreases in miners' profits will come more from increasing difficulty than from decreasing reward.

yes I see the chance of finding becuase hash up....

now hat if a lot of power is suddenly withdrawn can this difficulty readjust?

or are we stuck at that prime length dif

In any proof of work coin with an automatically adjusting difficulty there is a danger that a huge portion of miners could suddenly go off the network, leaving the difficulty high. In Bitcoin the network is stuck waiting for the 2016th block before difficulty can start readjusting down. Primecoin and others use a continuously readjusting method that allows the difficulty to start dropping immediately. That, combined with the much faster block generation time, means that Primecoin could handle a sudden outflux of miners better than many other coins.
