I’d think it a typo. It works out that they get $2766.66 each over two years.
Here’s the statistics section from the “Nazi Concentration Camps” page from Wikipedia for comparison:
There were 27 main camps and, according to Nicholas Wachsmann’s estimate, more than 1,100 satellite camps. (This is a cumulative figure that counts all the subcamps that existed at one point; Orth estimates the number of subcamps to have been 186 at the end of 1943, 341 or more in June 1944, and at least 662 in January 1945).
Around 1.65 million people were registered prisoners in the camps, of whom, according to Wagner, nearly a million died during their imprisonment. Historian Adam Tooze counts the number of survivors at no more than 475,000, calculating that at least 1.1 million of the registered prisoners must have died. According to his estimate, at least 800,000 of the murdered prisoners were not Jewish. In addition to the registered prisoners who died, a million Jews were gassed upon arriving in Auschwitz concentration camp; including these victims, the total death toll is estimated at 1.8 to more than two million. Most of the fatalities occurred during the second half of World War II, including at least a third of the 700,000 prisoners who were registered as of January 1945. In proportional terms, the death rate was highest in 1942 and fell again in 1943 before rising again during the last year of the war; however the increase in the number of prisoners meant that in absolute terms the number of deaths continued to rise.
