# Prime Sum

Problem Description

Given an even number ( greater than 2 ), return two prime numbers whose sum will be equal to the given number.
If there is more than one solution possible, return the lexicographically smaller solution i.e.
`If [a, b] is one solution with a <= b,and [c,d] is another solution with c <= d, then[a, b] < [c, d] If a < c OR ( a == c AND b < d ).`
NOTE: A solution will always exist. read Goldbach's conjecture

Problem Constraints
1 <= A <= 2 * 107

Input Format
The first argument is an integer A.

Output Format
Return an array of integers.

Example Input
4

Example Output
[2, 2]

Example Explanation
2 + 2 equals 4, which is the lexicographically smaller solution

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
