%N Primes not in A138980.

%C Except for the first term, the sequences A049561 and A138980 both consist of all odd primes except for 59, up to p=163 which is in A049561 but not in A138980.

%o (PARI) s=a=1;for(i=1,10^3,/*print1(","a);*/ while(isprime( s+a=nextprime(a+1) ),print1(a","));s+=a) /*using instead the commented-out print() command yields the sequence A138980.*/

%Y Cf. A138980, A138981.
