<var>
var
   T:integer;
   N,M:longint;
   i,y,pos:longint;
</var>
begin
	
	read(T);
	
	while T <> 0 do
	begin
	readln(M,N);
	
	for i := M to N do
	begin
	pos := ceil(sqrt(i));
	for y := 2 to pos do
	begin
	if i mod y = 0 then break
	else continue;
    end;
	if (i mod y <> 0) and (i > 1) then
	writeln(i);
	end;
	writeln;
	T := T-1;

it is due to ceil function ceil(sqrt(2))=2

hence your program breaks when i%y==0 (2%2==0)
