go - Moment of threads creation

Question

When is the moment when threads determined in runtime.GOMAXPROCS(n) will be created:

When we launch binary file amount of threads equals runtime.GOMAXPROCS(n) will be created immediately, for instance, runtime.GOMAXPROCS(n) == 8, and our program has 3 goroutines, which means 3 of 8 threads will be busy and 5 idle

or

Threads will be created on-demand as goroutines are created.
