Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520160, here are decompositions:

13 + 33520147 = 33520160
31 + 33520129 = 33520160
73 + 33520087 = 33520160
97 + 33520063 = 33520160
109 + 33520051 = 33520160
181 + 33519979 = 33520160
211 + 33519949 = 33520160
283 + 33519877 = 33520160

Showing the first eight; more decompositions exist.
