All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum.
11 cannot be written as the sum of two primes.
13 = 2 + 11.
17 cannot be written as the sum of two primes.
19 = 2 + 17.
There are 9592 primes.
There are infinitely many primes. There are 24 prime numbers between 1 and 100
There are no fixed differences. In fact, gaps between successive primes can be arbitrarily large. As of 2014, the largest prime gap between proven primes is 1,113,106. The two successive primes at either end have 18662 digits each. A larger gap, of 3,311,852 numbers between probable primes has been conjectured.
The primes between 150 and 200 are: 151,157,163,167,173,179,181,191,193,197, and 199
There are some patterns, but none that can help you determine, in all cases, whether the number is a prime or not.For example: * All primes except 2 are odd numbers. However, not all odd numbers are primes. * All primes greater than 3 are of the form 6n - 1, or 6n + 1. However, not all numbers of this form are primes.
Sixteen primes.
There are 9592 primes.
There are 19 primes.
The primes are 23, 29, and 31.
There is no limit: gaps between successive primes can be arbitrarily large. As of 2014, the largest prime gap between proven primes is 1,113,106. The two successive primes at either end have 18662 digits each. A larger gap, of 3,311,852 numbers between probable primes has been conjectured.

Every composite number ... that is, one that is not a prime ... can be written as the product of two or more prime numbers. The primes themselves are the exceptions. A prime number is the product of only ' 1 ' and itself, and ' 1 ' is not considered a prime number.

The only twin primes (prime numbers which differ by 2) between 30 and 60 are (41, 43)
The primes between 150 and 200 are: 151,157,163,167,173,179,181,191,193,197, and 199
There are 9 prime numbers between 0 and 20: 1,2,3,5,7,11,13,17,19.
