On a problem concerning the Smarandache left-rigth sequences

Let's now check if those primes are also additive. For the primes of the sequence SLRP we have that 4 out of 5 are additive being the sum of digits equal to 2, 41, 71 and 63 1 . The only prime that is not additive is that starting with 139 and ending with 149 which sum of digits is 296 that is composite. About the SLRNN sequence the only prime found is not additive because the sum of the digits is equal to 1027 that is a composite number. According to those results the following two conjecure can be posed: Conjecture 1: The number of additive primes inside the sequence SLRP is finite Conjecture 2: The number of additive primes inside the sequence SLRNN is null.
