Question:
what was the sum of the european papers net sales from 2006 to 2004


pre_text: printing papers net sales for 2006 decreased 3% ( 3 % ) from both 2005 and 2004 due principally to the sale of the u.s .
coated papers business in august 2006 .
however , operating profits in 2006 were 43% ( 43 % ) higher than in 2005 and 33% ( 33 % ) higher than in 2004 .
compared with 2005 , earnings improved for u.s .
uncoated papers , market pulp and european papers , but this was partially offset by earnings declines in brazilian papers .
benefits from higher average sales price realizations in the united states , europe and brazil ( $ 284 million ) , improved manufacturing operations ( $ 73 million ) , reduced lack-of-order downtime ( $ 41 million ) , higher sales volumes in europe ( $ 23 million ) , and other items ( $ 65 million ) were partially offset by higher raw material and energy costs ( $ 109 million ) , higher freight costs ( $ 45 million ) and an impairment charge to reduce the carrying value of the fixed assets at the saillat , france mill ( $ 128 million ) .
compared with 2004 , higher earnings in 2006 in the u.s .
uncoated papers , market pulp and coated papers businesses were offset by lower earn- ings in the european and brazilian papers busi- nesses .
the printing papers segment took 555000 tons of downtime in 2006 , including 150000 tons of lack-of-order downtime to align production with customer demand .
this compared with 970000 tons of total downtime in 2005 , of which 520000 tons related to lack-of-orders .

operating earnings in 2006 more than doubled compared with both 2005 and 2004 .
the benefits of improved aver- age sales price realizations more than offset higher input costs for freight , wood and energy , which were all above 2005 levels .
mill operations were favorable compared with 2005 due to current-year improve- ments in machine performance , lower labor , chem- ical and energy consumption costs , as well as approximately $ 30 million of charges incurred in 2005 for machine shutdowns .

manufacturing operations were favorable due to higher machine efficiency and mill cost savings .
u.s .
market pulp sales in 2006 were $ 509 mil- lion , compared with $ 526 million and $ 437 million in 2005 and 2004 , respectively .

brazil ian paper net sales for 2006 of $ 496 mil- lion were higher than the $ 465 million in 2005 and the $ 417 million in 2004 .
