Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505900, here are decompositions:

11 + 33505889 = 33505900
17 + 33505883 = 33505900
41 + 33505859 = 33505900
47 + 33505853 = 33505900
53 + 33505847 = 33505900
101 + 33505799 = 33505900
149 + 33505751 = 33505900
269 + 33505631 = 33505900

Showing the first eight; more decompositions exist.
