How to come up with a probability distribution knowing the mean value?

I would like to know about some algorithms or techniques to find a discrete probability distribution knowing the mean value. Let's say given the mean=2.5. The probability distribution can be $x_1=2, P(x_1)=0.5$ and $x_2=3, P(x_2)=0.5$ $x_1, x_2,..., x_i$ should have discrete values in the solution.
