%e a(1)=170 because first two 8-digit distinct-digit primes are 10234589 and 10234759 and difference between them is 170.

%t se=Select[Range[10234589, 98765431, 2], Length[Union[IntegerDigits[ # ]]]==8 &&PrimeQ[ # ]&]; Flatten[Table[{se[[i+1]]-se[[i]]}, {i, 90510}]]

%t Differences[Select[Prime[Range[679128,685000]],Length[Union[ IntegerDigits[#]]] == 8&]] (* _Harvey P. Dale_, Nov 12 2014 *)

%Y The eight-digit distinct-digit primes are in A074665.
