The chances are quite slim I suspect,
but sieving can be done quite easily.

I have started yesterday a sieve for the first 4 numbers left, and that one did 40Mp/sec (now only 3 left since a factor was found for 512k)

It will reach the limit of srsieve in about 1 day.
If some numbers are left, well... it's getting very hard to test them.

I will start a sieve for the next 4 after the first one finishes; that sieve-speed is significantly slower (About 7Mp/sec), but will finish in reasonable time too.
After that, I think I will let it go.
