The XB number axis was moved to the right by two number axis units and overlapped with the XA number axis in the same direction, and the characteristics of the number axis points of twin prime numbers were analyzed. By overlapping XA and XB in opposite directions, it was proved that the number of pairs of P(1,1) prime numbers that could be divisible by 6 was approximately equal to or more than the number of pairs of twin primes that were smaller than the even number.
