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.

Thank you for your reply. I wasn't sure I would get one.

Very well. I will just let this go then.

I am keen on sieve from the Leyland first kind (plus form) table a (x,Y) range
(15001,2000) to (20000,19999).

The largest Leyland number in your range is 86021 decimal digits. It has been claimed that all Leyland primes smaller than 150000 decimal digits are known. See my table of Leyland primes here. To generate a 150000-digit (or larger) Leyland number, x can not be smaller than 33180.
