%N A229570 Primes of form p*q + 30, where p and q are consecutive primes.
%C A229570 Conjecture: The expression p*q + c with p and q consecutive primes and c = 30 generates more primes than any other value of c in the range 1 < c < 100 and p = 48611 which is 5000th prime. Hence, c = 30 is considered for this sequence.
