If "Viktor/Victor" means 'winner', and "Nikifor" is derived from the Slavic version Greek as "Nikiforos/Nicephorus/Nikephorus" meaning 'bringer of victory', AND "-ov" is 'son of', meaning, Viktor Nikiforov, basically means 'Winner Winnerson'.
Again, let me scream.
Viktor/ Viktor = Winner
Nikifor = Bringer of victory
-ov = son of
This lil shit,,,,
BONUS
Katsuki = Born to win
Yuuri = Courage to win
Ergo, after the marriage, their names will either be:
(Viktor Nikiforov-Katsuki) Winner Winnerson-Born To Win,
OR
(Yuuri Katsuki-Nikiforov) Courage To Win Born To Win-Winnerson.
