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.
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.
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 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.
