x+y=54
x-y=20
solving it,we get x=37 and y=17
5
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.
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.
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.

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.
The difference when subtracting the prime number 2 from the prime number 127 is 125. No other two prime numbers added together or subtracted from each other have a sum or difference of 125. All primes except the number 2 are odd numbers, and two odd numbers added together or subtracted will always produce an even sum or difference.
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.
5; (3 + 2 and 7 - 2)
23 and 29
The sum of the first two prime numbers is 5.
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
