Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505020, here are decompositions:

11 + 33505009 = 33505020
13 + 33505007 = 33505020
19 + 33505001 = 33505020
37 + 33504983 = 33505020
79 + 33504941 = 33505020
139 + 33504881 = 33505020
193 + 33504827 = 33505020
223 + 33504797 = 33505020

Showing the first eight; more decompositions exist.
