I am sure that this has already been done and discussed on this forum. (1e6 to 2e6 range)

One just needs to carefully read this subforum. If it sounds like work, - yes. It. Is! With careful reading one can save CPU years.

If you still want to do it from scratch, then you need to take a snapshot of all <106 sequence's endpoints and check if/when your new sequence merges - immediately. It is extremely easy to do with FactorDB REST call (e.g. , parse and check against known endpoints. Done!). Then such merges to be added to a separate table to be posted some place in this forum, but not to be exposed it in the system.You will have a few percent of all even numbers surviving this simple procedure.
