trial and error, also called guess and check, but not quite

let x = 1st odd prime, and y = 2nd odd prime

the y can be 1,3,5,7,11,13,17,19,23,29,31

then x+y = 36, or x = 36 - y, by substitution

x = 36 - 1 = 35 not prime so not a solution

x = 36 - 3 = 33 not prime

x = 36 - 5 = 31 prime

x = 36 - 7 = 29 prime

x = 36 - 11 = 25 not prime

x = 36 - 13 = 23 prime

x = 36 - 17 = 19 prime

x = 36 - 19 = 17 prime (but a repeat of another solution)

so (5+31), and (7+29), and (13+23), and (17+19) are all solutions

For your question about the method, maybe it is called the method of exhaustion. List all possibilities for one number and exhaust (solve and check) for all other solutions.

How many of the prime numbers between 10 and 20 can be written as the sum of two primes?

All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.

Is the sum of prime numbers cannot be a prime?

Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.

Express 46 and 38 as the sum of two odd primes?

To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
