Dark green = Riesel k, i.e. proven no primes
Light blue = no known primes for k

Box = 30th prime for k
Black = generalized Woodall prime, i.e. n*10^n-1
Orange = twin prime with k*10^n+1
Salmon = twin prime with k*10^n-3
Light yellow = Sophie Germain prime with 2k*10^n-1
Dark yellow = Sophie Germain prime with k/2*10^n-1
