How many F-22 would it take to shutdown MiG-25RBS reconn flights?

We know six MiG-31B could box in an SR-71, but how many F-22 would it take to box in the Russian MiG-25RBS counterpart? The F-14A and F-15A could both deny free access to the MiG-25R direct overflights, but the RBS has much improved slant range of it’s sensor suite. The RBS is much more comparable to the SR-71, mapping wide swaths of land with each pass.
