Not sure if it is what you are looking for but if you play with backtesting tab on bustabit site (you don't even need to log in to see it) you can generate games based on a historical hash : you can flag "historical games" and choose the number of games you desire.
I just used it few times so dont know if it can simulate up to 1 million games : try your luck there and let us know if you solved.
Thanks, but this is not what I am looking for. I want to have the data on my computer. I tried to run this on my local machine, but I failed:
