Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505220, here are decompositions:

43 + 33505177 = 33505220
97 + 33505123 = 33505220
103 + 33505117 = 33505220
163 + 33505057 = 33505220
181 + 33505039 = 33505220
211 + 33505009 = 33505220
433 + 33504787 = 33505220
457 + 33504763 = 33505220

Showing the first eight; more decompositions exist.
