Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609920, here are decompositions:

7 + 33609913 = 33609920
13 + 33609907 = 33609920
103 + 33609817 = 33609920
151 + 33609769 = 33609920
163 + 33609757 = 33609920
199 + 33609721 = 33609920
271 + 33609649 = 33609920
313 + 33609607 = 33609920

Showing the first eight; more decompositions exist.
