I've tried looking into moment generating functions, of which my knowledge is lacking, but stumbled upon a question claiming (and proving) that there is no such function. ( link)

Here's what's happening: for any discrete random variable X, the expected value E [ X] is ∑ i P ( X = i), as you noted.
