Thanks.

Another LUCKY result, I would say :-) At the moment I have the
following solution count:
5 links or longer: 1022
6 links or longer: 42
7 links or longer: 3

Given that the additional link appears in 4-5% of solutions, the
expected nuber of 7-linked solutions is 2 and the expected number of
8-linked solutions is around (or even slightly below) 0.1.

Fantastic find, so jealous.

And which, in its elemental form k=N/4=28127920617695618244525
has 2^4+k and 2^6+k prime.
