Question about A075849

[Mark Hudson]

Hi,

I've been lurking on this list for a while now for fear of looking stupid, 
but I have a query about A075849:

%I A075849
%S A075849 2,1,0,0,1,0,1,0,1,2,1,0,1,2,1,0
%N A075849 Distance to closest prime.
%e A075849 a(34)=3
%K A075849 nonn,more,new
%O A075849 0,1

I have been working on the basis that a(0)=2 because the nearest prime to 0 
is 2 and so is 2 away.
Likewise, a(prime)=0.

So... why is the 14th digit in the above sequence, which should be a(13), 
not equal to 0? And shouldn't a(15)=2?

Mark.
