Eight pairs. Two prime numbers M and N are twin primes if |M-N| = 2. So here are the list of prime numbers less than 100:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
There are 8 pairs of twin primes here:
- 3,5
- 5,7
- 11,13
- 17,19
- 29,31
- 41,43
- 59,61

How many prime numbers between 1 and 8888888888888888888888888888888888888888888888?
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
