Hello SeqFans
 
http://oeis.org/classic/A055265 <http://oeis.org/classic/A055265> 
says:
"Smallest positive integer not already in sequence with a(n)+a(n-1) prime."
 
If we change "positive" into "non negative integer" we'll get another seq:
 
S=0,2,1,4,3,8,5,6,7,10,9,14,15,16,13,18,11,12,17,...
 
...which might merge at some point with A055265, who knows?
 
Again, a few more terms and a co-submission would be great!
Best,
É.
