Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505212, here are decompositions:

89 + 33505123 = 33505212
109 + 33505103 = 33505212
163 + 33505049 = 33505212
173 + 33505039 = 33505212
211 + 33505001 = 33505212
229 + 33504983 = 33505212
271 + 33504941 = 33505212
283 + 33504929 = 33505212

Showing the first eight; more decompositions exist.
