I did my own sieving. I wasn't even aware they had sieved k=2293 for 12e6 <= n <= 15e6.

Ryan, you're aware of the Wiki and also got an account: please let us know your searched ranges here or in the Wiki to avoid doblechecks or doing others work. On your Personpage there're several reserved values, but only found primes are known, no ranges.
I'm trying to keep those data for history and for others to make searches in such high ranges not disappointed for anybody. Filling in missing/not known ranges in prime search is a unlikely work for everybody but to keep it scientific under the aspect of a mathmatical proof it's necessary.
