# Representation of e in terms of primes

We can represent π, in terms of primes by using Euler's product form of Riemann Zeta.
For example ζ(2)=(π^2)/6= ∏ p^2/(p^2-1).

Likewise, is there a representation of e that is obtained by using only prime numbers?

I guess there is no such known representation?
