Gaps in my current table generally represent untested numbers. However, in this instance I will have finished looking at candidates up to 386700 digits by next week, so far without a find. I had no intention of looking beyond that.

Thanks for the info.
I do not want to do uncontrolled Sieve range or solo work out of the blue here. To messy. Any gabs to close maybe if that will help ?
