4. In the picture, there is a special playing die. The numbers on opposite sides always add up to the same sum. The numbers we don't see in the picture are prime. What number is opposite the number 14, and which number is opposite the number 18?

First method:

Since the numbers 14 and 18 are even, and the numbers opposite them are prime, we conclude that the sum of the numbers on opposite sides must be odd.

Opposite the number 35 must be an even number, and the only even prime number is 2.

The sum of the numbers on opposite sides is always 37 (35 + 2).

Opposite the number 14 is $37-14=23$, and opposite the number 18 is $37-18=19$. \quad 2 POINTS
