In this program, you'll learn to check whether a given number can be expressed as a sum of two prime numbers or not. This is done with the help of loops and break statements in Kotlin.

To accomplish this task, `checkPrime()`

function is created.

The `checkPrime()`

returns 1 if the number passed to the function is a prime number.

```
fun main(args: Array<String>) {
val number = 34
var flag = false
for (i in 2..number / 2) {
// condition for i to be a prime number
if (checkPrime(i)) {
// condition for n-i to be a prime number
if (checkPrime(number - i)) {
// n = primeNumber1 + primeNumber2
System.out.printf("%d = %d + %d\n", number, i, number - i)
flag = true
}
}
}
if (!flag)
println("$number cannot be expressed as the sum of two prime numbers.")
}
// Function to check prime number
fun checkPrime(num: Int): Boolean {
var isPrime = true
for (i in 2..num / 2) {
if (num % i == 0) {
isPrime = false
break
}
}
return isPrime
}
```

When you run the program, the output will be:

34 = 3 + 31 34 = 5 + 29 34 = 11 + 23 34 = 17 + 17

Here's the equivalent Java code: Java Program to Repesent a Number as a sum of two numbers.
