%N Lesser of a pair (p,p+4) of cousin primes whose arithmetic mean p+2 is a cube.

%C p = n^3 - 2, p and p+4 are "near(est) cube" primes as n^3 -/+ 1 = (n -/+ 1) * (n^2 +/- n + 1)

%e p=2146687 is a term, as p+2=129^3 and both p=129^3-2 and p+4=129^3+2 are prime.

%o (PARI) isok(p) = isprime(p) && (q=nextprime(p+1)) && (q-p==4) && ispower(p+2, 3); \\ _Michel Marcus_, Nov 27 2016

%Y Cf. A046132, A172494, A174370, A176130, A176229.
