It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
If you meant "what two prime numbers have a sum of 36?" the answer is 19 and 17.
Two prime numbers can have only one sum, not three different sums!
No.
If two prime number have a sum of 54 they cannot have a sum of 84, and conversely.
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
If you meant "what two prime numbers have a sum of 36?" the answer is 19 and 17.
The sum of the first two prime numbers is 5.
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
Three and Seven
The sum of the two prime numbers 3 and 73 is 76.
I assume you are asking the question "what two prime numbers sum to 44". There may be other pairs of prime numbers that sum to 44, but 37 and 7 are both primes and their sum = 44.
There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.

The sum of two prime numbers will be composite unless one of the prime numbers is 2.
