Do you know of any others? If there are others, you could make a sequence out of it. I think the site asks for a minimum of 4 terms.
If you can't find any others, maybe it could go into Prime Curios:
I wouldn't describe it as "less interesting" at all.
I noticed that A030469 and A167676 have almost exactly the same description, but one term, 171923, is in one but not the other.

Probably "less" interesting as OEIS goes, but I've checked that
353359367 is the smallest emirp which is a concatenation of three
Reverse A167676(12) = R(353 concat 359 concat 367) = R(353359367) =
763953353 is prime.
That is: A167676 INTERSECTION A006567.
