%N Primes of the form (k-th primorial) - (k+1)st prime.

%C Conjecture: sequence is infinite.

%e primorial(4) - prime(4+1) = 2*3*5*7 - prime(5) = 210 - 11 = 199, which is prime, so 199 is a term.

%Y Cf. A002110, A093078, A249798 (corresponding k's).

%Y The prime numbers in A060882.

%Y A038708 with subtraction instead of addition.

%K nonn

%O 1,1
