[seqfan] Need help understanding Orlovsky's A154734 and A154736

[Neil Sloane]

I just edited A154731, A154732, A154733, which were pretty easy.

Then I ran into A154734 and A154736 and got an instant headache.
Could someone who speaks Mma kindly edit these entries?
A154734 Integers k of the form k=n^2-k, such that k-+1 are primes,k(0)=2.
A154736 Integers n such that (k=n^2-k)-+1 are primes,k=2.
