What else can I help you with?
Write 100 as the sum of two primes in six different ways?
100 = 62 + 82 = 82 + 62 and there is no other way
Write the number 12 as the sum of two primes?
12=5+7
What are even nos between 100 to 300 that is the sum of two prime nos?
Each one of them can be expressed as a sum of two primes.
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
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.
Write the number 18 as the sum of two primes?
1 + 17 = 18 5 + 13 = 18 7 + 11 = 18
The sum of two odd number is?

It is: 2+13 = 15
What is the smallest prime number that is the sum of two primes?
5
What even number is not the sum of two primes?
16
Express each what as sum of two odd primes a92?
To express 92 as the sum of two odd primes, we can try various combinations of odd primes. One such combination is 89 and 3, since both 89 and 3 are prime numbers and their sum equals 92. Another combination is 83 and 9, but 9 is not a prime. Thus, 92 can be expressed as the sum of the odd primes 89 and 3.
Is the sum of two prime numbers always a prime numer?
It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.
