Is the 67th power of 2 minus 1 prime I want to know the answer

One is 193707721 × 761838257287, and the other is 67th power-1 of 2. The results of the two formulas are exactly the same. Since it is equal to the product of two numbers and can be decomposed into two factors, it is proved that 67th power-1 of 2 is not a prime number, but a composite number
Remember that a formula 2 ^ (5N) - 1 is prime
