Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520280, here are decompositions:

7 + 33520273 = 33520280
61 + 33520219 = 33520280
151 + 33520129 = 33520280
193 + 33520087 = 33520280
229 + 33520051 = 33520280
331 + 33519949 = 33520280
337 + 33519943 = 33520280
373 + 33519907 = 33520280

Showing the first eight; more decompositions exist.
