Probably it's hard to find because there has never been such a person at the head of KGB? There had been 8 chairmen (K in KGB stands for "committee" hence its head's title is "Chairman") in the whole history of this organization and none of them had this or similar name. The only KGB-related person with such name is Yevgeni Maksimovich Primakov, who had been a head of the KGB's 1st Department for a brief period of time in 1991, but he had been a civilian so not the same person as the "General Yevgeni Primakov".
