Neighborhoods of most primorials (=center) are either empty or poor of primes. The listed primes arise if center=A002110(A096833(n)), while radius=ceiling(log(center)).
The subsequent terms are too large to include: a(6) = A002110(66)-1, which has 131 digits. a(7) = A002110(68)-1, which has 136 digits. a(8) = A002110(75)+1, which has 154 digits. - David Wasserman, Nov 16 2007
