%N Nonprimes of the form ((x+y)/3+2)/(x-y), where x=prime and y=nonprime.
%C x=p(i)=i-th prime and y=n(j)=j-th nonprime.
%e If x=5 and y=1, then ((5+1)/3+2)/(5-1)=4/4=1=a(1).
%e If x=53 and y=49, then ((53+49)/3+2)/(53-49)=36/4=9=a(2).
%e If x=59 and y=55, then ((59+55)/3+2)/(59-55)=40/4=10=a(3).
%e If x=89 and y=85, then ((89+85)/3+2)/(89-85)=90/4=15=a(4).
%e If x=149 and y=145, then ((149+145)/3+2)/(149-145)=100/4=25=a(5).
%e If x=179 and y=174, then ((179+174)/3+2)/(179-174)=120/4=30=a(6),
