It even seem sthat the terms after 3313 are plain wrong.
Or did I miss something in the following pari computation:

P=prod(k=1, 1000, 1+x^k, 1+x*O(x^1000));
for(n=1,1000,t=n+polcoeff(P,n);if(isprime(t),print1(t,",")))

2,3,5,17,23,31,73,97,127,167,191,797,1021,1153,1301,3313,9851,40099,206939,

Apparently, 281641, 451331, 966527, ... do not occur.
