I'm trying to find the sum of primes below million

I'm trying to find the sum of primes below millions..my code works when I
try to find the sum of primes below hundred thousands but when I go large
numbers it doesn't work....so I need some help to get this work for big
numbers...
import java.util.Scanner;
public class sumPrime {
public static void main (String args []){
long n = 2000000; int i; int j;int sum =0;
for (i=2; i <n; i++){
for (j=2; j<i; j++){
if (i%j==0){
break;
}
}
if (i==j){
sum +=i;
}
}
System.out.print(sum);
}
}
