Second Su-37?

Hi mates,
I hope somebody here is in the know and can answer me the following question:
Was ever another Su-27M except for board number 711 designated Su-37? I think not, but a discussion on another forum reminds me on the "second" Su-37. It was reported many years ago that a second Su-37 was built. It must be board number 712, but was this aircraft ever designated Su-37 or was it misinterpreted by the fact that the aircraft was built after the 711? Or do I messing up something here?

thanks in advance

711 was the only Su-37 demonstrator. 712 was primarily an avionics testbed, although I think it trialled some new engines as well at one point.
