What output will the program produce in example №41

Determine what text will be output to the console after executing the following Go program:

import (
    "fmt"
)
func main() {
    var highest int

    for counter := 1000; counter > 0; counter-- {
        go func() {
            if counter%2 == 0 && counter > highest {
                highest = counter
            }
        }()
    }
    fmt.Println("Maximum is %d", highest)
}

Pay attention to the behavior of goroutines and variable capture in the loop.
