Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520180, here are decompositions:

11 + 33520169 = 33520180
53 + 33520127 = 33520180
137 + 33520043 = 33520180
149 + 33520031 = 33520180
167 + 33520013 = 33520180
251 + 33519929 = 33520180
257 + 33519923 = 33520180
389 + 33519791 = 33520180

Showing the first eight; more decompositions exist.
