How to use sed to find a path and concatenate the output with a string

I would like to add a string to a sed output to form the complete path, I am not sure how I can concatenate the string to the result, how should I modify the following command? Any help would be appreciated.

$ go env | grep GOPATH | sed 's/.*="\(.*\)"/\1/'

/Users/Paul/go

# Would like to add /bin/hello to the above path with the end result
/Users/Paul/go/bin/hello

You could do this in a single awk itself. My go env output has GOPATH like GOPATH="/root/go" so I have taken care of " part here, new values will be added before last " by awk.

go env |  awk '/GOPATH/{gsub(/^GOPATH="|"$/,"");$0=$0 "/bin/hello";print;exit}'

2nd solution: Using sed you could try following here. Stop printing of lines by -n option of sed and print only matching line which has GOPATH in it, along with new values attached to it.

go env | sed -n '/GOPATH/ s|.*="\(.*\)"|\1/bin/hello|p'
