The hit was prp64853 = (3045*2^215472-2)/(2*17*1151*27067*173473).
Chris Chatfield found 3045*2^215472-1 in 2005:

probably only few hits left on known primes.
I don't expect to search above the ongoing twin prime search at
k*2^333333+/-1 - at least not before they actually find a twin and set
a record. By then there will also be a Chen prime record to retake...
