No. For an odd number, usually you would need to add at least three prime numbers.The Goldbach conjecture states that every EVEN number can be written as the sum of two prime numbers. This conjecture hasn't been proved or disproved so far, but many even numbers have been checked, and so far, it seems to be true.

Is every prime number a rational number?
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Is Every whole number greater then 1 can be written as the sum of two prime numbers?
true
What is every whole numbers greater than one is either a prime number or can be written as a product of a prime number in an unique way?
The Fundamental theorem of arithmetic.
What is the largest prime number that can be written as the sum of two prime numbers and the difference of two prime numbers?
5
Is every number in the nineties composite or prime what the correct?
The only prime number in the 90s is 97. So out of ten numbers one is a prime number and the remaining nine numbers are composite numbers. So 90s comprises of both prime numbers and composite numbers.
What is the term for every composite number can be written as a product of prime numbers?
the prime factorization
Every number from 1 to 100 can be written as the sum of two prime numbers?
No.
Can every composite number be written as a product of prime numbers?
Yes, by definition!
Can every number be written as the sum of 2 prime numbers?
1 can't.
Is every prime number a rational number?
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Can each of the whole numbers between 1 and 50 be written as a product of two or more prime numbers?
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.
Is Every whole number greater then 1 can be written as the sum of two prime numbers?
true
Can every whole number greater than one be written as the sum of two prime numbers?
No.
What is every number greater then 1 can be written in prime factorization form?
Those are composite numbers.
If every number is a prime number what are the three numbers?
The premise of your questions is false: NOT every number is a prime number.
Can every square from 5-15 be written as the sum of 2 prime numbers?
There is only one square number from 5-15: 9. This can be written as the sum of 2 and 7, which are prime numbers.
What is every whole numbers greater than one is either a prime number or can be written as a product of a prime number in an unique way?
The Fundamental theorem of arithmetic.
