Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581920, here are decompositions:

59 + 33581861 = 33581920
83 + 33581837 = 33581920
101 + 33581819 = 33581920
107 + 33581813 = 33581920
179 + 33581741 = 33581920
227 + 33581693 = 33581920
233 + 33581687 = 33581920
347 + 33581573 = 33581920

Showing the first eight; more decompositions exist.
