What two prime numbers equal 87?
All prime numbers except for 2 are odd. The sum of any two odd numbers is even. Therefore, unless 85 is prime (it's not) or -2 is, (it's not) there aren't two prime numbers that will equal 87.
When you add two prime numbers why do you get an even number?
You don't always. 2 + 5 = 7, for example. But all prime numbers other than 2 are odd and two odd numbers always equal an even number when added together.
Can 2 prime numbers equal 25?
For two numbers to equal an odd number, you need one to be even and the other odd. In this case, we want both to be prime. The only even prime number is 2. Therefore, the other number must be 23. This is prime, and so yes, 2 prime numbers can equal 25, however 2 and 23 are the only possible pair.
Are more prime numbers even or odd?
Odd. The only prime number that is even is two. Since there are many prime numbers that are odd (such as 3, 5, etc.), there are more odd prime numbers than even.
Are most prime numbers also odd numbers?
All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.

What 2 prime numbers equal 469?
Other than the number 2, all other prime numbers are odd. As 469 is odd then it must be formed by the addition of an even number (2) and an odd number (467). The two prime numbers are thus 2 and 467.
When you add two prime numbers why do you get an even number?
You don't always. 2 + 5 = 7, for example. But all prime numbers other than 2 are odd and two odd numbers always equal an even number when added together.
All prime numbers except for 2 are odd?
All of the prime numbers are odd except for two.

Odd. The only prime number that is even is two. Since there are many prime numbers that are odd (such as 3, 5, etc.), there are more odd prime numbers than even.
When you add two prime numbers together why do you get an even number?
You don't always. 2 + 5 = 7, for example. But all prime numbers other than 2 are odd and two odd numbers always equal an even number when added together.
Are most prime numbers also odd numbers?
All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.
What makes odd prime numbers?
Prime numbers are integers that are not divisible by anything except one and themselves. All prime numbers (excepting two) are odd.
Can the sum of two odd prime numbers ever be prime?
No.
What is an odd prime number?
Odd numbers end in 1, 3, 5, 7 or 9. Prime numbers have only two factors. 47 is an odd prime number.
What 2 consecutive odd numbers when added together equal the product of the 1st and 4th prime number?
The product of the first and fourth prime numbers (2 x 7) is 14. No two consecutive odd numbers add up to 14.
