%N A120850 Numbers n such that n is prime and is equal to the sum of the first k primes plus the product of the first k primes, for some k.
%C A120850 It is in the spirit of A096342 (only for 2 consecutive primes) and of A013918 (all primes but only the sum).
%C A120850 The corresponding values of k are 2, 4, 6, 60, 96, ... - _Amiram Eldar_, Dec 19 2018
