The odd primes less than 20 are: 3 5 7 11 13 17 19
There are 8 twin primes less than 100. 3,5 : 5,7 : 11,13 : 17,19 : 29,31 : 41,43 : 59,61 : 71,73
In any large range of numbers, more so the higher and larger the range is, there will be more composites than primes. It is far more likely that a given number will be divisible by some number less than the number itself, the higher you go.
5, 7, 13, 17 and 19 can be so written.
Just 7. Any other number divisible by 7 isn't prime.
