How many go routines will be created at runtime?

In an interview today, I got a problem to write a program with 2 goroutines to generate even and odd sequence and synchronize them to print the sequence of number.

Later, I was asked how many routines will be created. I answered 2 routines if we don't count the main().

But the interviewer was of differing opinion!

I tried with debugger too and found that there are 2 routines.

Is there anything that I am not seeing?

import (
    "context"
    "fmt"
    "sync"
    "time"
)

func main() {

    ctx := context.Background()
    ch := make(chan int, 1)

    go func() {
        for {
            odd(ch)
            even(ch)
        }
    }()

    wg := &sync.WaitGroup{}
    wg.Add(1)
    go func() {
        defer wg.Done()
        for {
            time.Sleep(1 * time.Second)
            select {
            case <-ctx.Done():
                return
            case d, ok := <-ch:
                if !ok {
                    fmt.Println("channel is closed")
                    return
                }
                fmt.Println(d)
            }
        }
    }()
    wg.Wait()
}

var n1 int = 1

func odd(ch chan<- int) {
    ch <- n1
    n1 += 2
}

var n2 int = 2

func even(ch chan<- int) {
    ch <- n2
    n2 += 2
}
