The median value of [1, 2, 3, 4] is 2.5

  Sure, but 2 is the only even prime, so this is super constrained.

  That's the mean.

    And it’s also the median.

      Depends if you are looking at a mean closed to integers or not: one can define a mean without rational or real numbers.

  But the median of [1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 4] is 2. As the individuals observed values collect more and more repetitions—as they do when making a list of the second prime factor, for example—it becomes increasingly unlikely that the median will be between two values, not equal to one of the values. It would be surprising if the median second prime factor was not a prime.
