Thanks for pointing it out, I did this over an IPython session and copied it in a (completely unnecesary) hurry. The results are good though :)

Edit: as to keep my claim that the results are good, check this sentence from the article "...Nor could it explain why, as the pair found, primes ending in 3 seem to like being followed by primes ending in 9 more than 1 or 7." -- it backs up the data I posted :)
