Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520020, here are decompositions:

7 + 33520013 = 33520020
41 + 33519979 = 33520020
71 + 33519949 = 33520020
97 + 33519923 = 33520020
113 + 33519907 = 33520020
181 + 33519839 = 33520020
227 + 33519793 = 33520020
229 + 33519791 = 33520020

Showing the first eight; more decompositions exist.
