Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553920, here are decompositions:

11 + 33553909 = 33553920
19 + 33553901 = 33553920
41 + 33553879 = 33553920
83 + 33553837 = 33553920
149 + 33553771 = 33553920
151 + 33553769 = 33553920
173 + 33553747 = 33553920
181 + 33553739 = 33553920

Showing the first eight; more decompositions exist.
