If I skip 5 and 8 in my circle: PRIMES: 1860, CMAX = 21258 > 19690.
Greater number of primes doesn't necessarily mean higher score of the circle.
Also, below 8300 for the min so far.

What did you code in? What was the total runtime?
I coded in Python, it took ~24 minutes to solve the n = 7, d = 5 case. Java should be faster for sure....
