Thanks for the info. I have now submitted the following comment to
Neil Sloane.

%I A096548
%S A096548 7,289,7,33603,309403
%C A096548 Daniel Heuer found a(5) in Jan 2004 by sieving up to 10^33
and then checking ~8000 candidates with pfgw-linux. Proving primality
of 10^99999+309403 is beyond current (July 2004) technology.
