    Default 'for' loop problem

    i need to create a progam that enters even integers until the input number is reached. for some reason i think my for statement(for (int i = 2; i < x; i+= 2)) is messed up because it returns 18 intstead of 20 when 10 is entered. ive played around with this program to try to get it to work for several hours and i just can't find the solution. any pointers?
    import java.util.Scanner;
    public class EvenSum {
     
    	public static void main(String[] args) {
    		Scanner scan = new Scanner(System.in);
    		double x, sum = 0;
    		System.out.println("Enter number: ");
    		x = scan.nextInt();
     
    		for (int i = 2; i < x; i+= 2){ 
    			sum = i + x;		
    	}
     
    		if(x < 2){
    			System.out.println("Cannot enter number less than 2.");
    			System.exit(0);}
     
    		System.out.println("Sum of all evens is: " + sum);
    	}
    }
    thanks in advance
