Prime Number Story #2

2, the Queen of RPNK, thought and thought. At that time, 3 made a nice proposition. He said that
"Let's just fight! The Queen of RPNK."
Queen was frightened, because the army of NNK were so huge! She asked to 3.
"Why do you think like that? Look at the army of NNK! They are so huge!"
3 replied: "No, ma'am. We can win them. Their army's number of people are same as us, so we can win them! At least, we can make a draw!"
Queen couldn't understand 3. She asked again.
"Look up to 100. We only have 25 soldiers, but they have 75 soldiers!"
"No, ma'am think of 1."
"Okay. But, it's still 25 to 74. And look at 101 to 200! It's 21 to 79! How about from 7801 to 7900! It's 10 to 90! We can't win them!"
"No, no, no, ma'am. The number of soldiers of NNK is infinite. I know. But, the number of soldiers of ours is infinite, too!"
Queen couldn't understand more.
"But... how?"
