Step 1. Sieve a little (plain srsieve)
Step 2. Use dump_algebraics.pl (!) -- this S410 is the poster case for it. It will report all n :: 4|n. (or simply use awk or perl)
Step 2a. Remove them (with srfile)
Step 3. Continue sieving with sr1sieve, as usual, ...and then with llr.

That was first thing I do!
:bow::bow::bow: for algebraics.pl
You are then man!
