%N A178337 Numbers k such that (k^3 + 2, n^3 + 4) is a twin prime pair.
%C A178337 With the exception of k = 1, all k are odd multiples of 3 with a least-significant decimal digit of 3, 5 or 9.
%C A178337 A178336(n) gives the values of k^3 + 2.

%e A178337 1^3 + 2 = 3 = prime(2) and 3+2 = prime(3) are twin primes, so n=1 is a term.
%e A178337 45^3 + 2 = 91127 = prime(8811) and 91127+2 = prime(8812) are twin primes, so 45 is a term.
%e A178337 10893^3 + 2 = 1292535591959 = prime(48144179941) is a lower twin prime, so 10893 is a term.
