Prime[Random[Integer, {1, 1229}]]

Or on the HP Prime (pun intended):

ithprime(rand(1229)+1)

Albert and John: the target is generating primes between 1000 and 9999. So the lowest index is 169 (for 1009) and the highest is 1229 (for 9973). I don't use Mathematica or the Prime, but I think you will know the correct syntax for a random index between 169 and 1229 (inclusively).
