%N Natural numbers equal to the sum of two consecutive semiprimes (A118717), but not an integer multiple of a previous term.

%C Essentially A118717 with the multiples removed.

%e A118717(16)=95 is not in the sequence since 95=5*A181529(3).

%e A118717(17)=100 is not in the sequence since 100=10*A181529(1).

%Y Cf. A118717.
