Remote Akka Cluster that Calculates Prime Numbers

The akka-sample-cluster-app tutorial found in Typesafe Activator has been confusing and frustrating to work with. There are multiple examples inside the project and each example is configured to run locally instead of remotely. I have two Raspberry Pi 3's that I've configured with Java 8, Akka, and Scala, along with my Desktop computer. I need someone to help me get my Raspberry Pi cluster up and running with a small demonstration that returns all prime numbers from 1 to 1000 to my Desktop computer (where I'm running this all from). The ideal candidate will have experience with Akka Clusters, Scala, SBT, and Linux, and will create a new and better project for what I'm trying to do rather than use the one provided by Typesafe. In other words, I do not want a modified akka-sample-cluster-app project and will not accept proposals that only plan on modifying it.
