GO concatenate string with int

I’ve the following code which needs to get int value and add it to a string with string suffix. E.g.

At start I'm getting this

"fds data "

After the if statement it should like this 

"fds data 10 M"

This is the code:

ltrCfg := "fds data "
if len(cfg.ltrSharedDicts) > 0 {
    ltrCfg += strconv.Itoa(cfg.ltrSharedDicts["c_data"])
    ltrCfg += "M"
} else {
    ltrCfg += "10M"
}
out = append(out, ltrCfg)

ltrCert := “fds data "
if len(cfg.ltrSharedDicts) > 0 {
    ltrCert += strconv.Itoa(cfg.ltrSharedDicts["d_data"])
    ltrCert += "M"
} else {
    ltrCert += “20M"
}
out = append(out, ltrCert)

The code is working but I wonder for the first fork of the if statement

if len(cfg.ltrSharedDicts) > 0 {
    ltrCfg += strconv.Itoa(cfg.ltrSharedDicts["c_data"])
    ltrCfg += "M"

Is there a better way to achieve it?

For readability, I would write:

cd, ok := cfg.ltrSharedDicts["c_data"]
if !ok {
    cd = 10
}
out = append(out, fmt.Sprintf("fds data %dM", cd))
