Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505980, here are decompositions:

19 + 33505961 = 33505980
29 + 33505951 = 33505980
41 + 33505939 = 33505980
73 + 33505907 = 33505980
97 + 33505883 = 33505980
113 + 33505867 = 33505980
127 + 33505853 = 33505980
181 + 33505799 = 33505980

Showing the first eight; more decompositions exist.
