I will say this: in 2009 russian MoD signed a contract with UAC for production of 48 Su-35 planes. Back then, the Ruble was fairly strong, at some 30-ish Rubles for a dollar. The contract was signed for the sum of 66 billion rubles. Translating to some 40-ish million of then year dollars for a plane.
In 2015 another contract for another 48-50 Su-35 was signed. Back then Ruble went down in value, and was something like 65 Rubles per dollar. 48-50 planes were signed for some 100 billion rubles. Translating to some 31 to 32 million US dollars, in then year value.
It is normal the price would come down as the production ramps up, the same thing happens with any new plane.
In 2020 another contract was signed but sadly this one included a bunch of support stuff for the whole fleet as well, besides the naked planes, so the sum is not directly comparable to previous sales.
Various foreign sales of both russian or US gear are terrible examples to use, as there's too many possible and unknown variables included. For US and Russian own sales, there is at least a decent chance that both are fly away price sales, fairly comparable to each other. Of course both require bunch of other stuff and additional sales, but at least they should be comparable.
