The primes under 60 is:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59.
So 60 can be expressed as 53+7 , 47+13, 41+19 , 37+23 or 31+29.
In older days, 1 was considered prime - therefore 1+59 would also be a valid answer.

There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
7+3
The two prime numbers that have a sum of 62 are 31 and 31. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. Since 31 is a prime number and the only way to express 62 as the sum of two prime numbers is 31 + 31, the answer is 31 and 31.
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.
