There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
1 + 297 + 2311 + 1913 + 17
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 the first two prime numbers is 5.
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.
There are three pairs.
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.
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
Two prime numbers can have only one sum, not three different sums!
If two prime number have a sum of 54 they cannot have a sum of 84, and conversely.
The sum of any pair of prime numbers greater than 2 is an even number.
16prime + prime = (sum) sum is 16or13 + 3 =16
The sum of two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.
The sum of the two largest prime numbers less than 71 is 128.
17 and 3 are two prime numbers whose sum is 20. Their product is 51.
