These are similar to the Woodall primes, A050918, which are primes of the form n*2^n - 1.
EXAMPLE
3 = 0*2^0 + 3; 5 = 1*2^1 + 3; 11 = 2*2^2 + 3; 67 = 4*2^4 + 3
MAPLE
#choose N large, then S is the desired set
f:=n->n*2^n + 3:
S:={}:
for n from 0 to N do if(isprime(f(n))) then S:=S union {f(n)}: fi: od
