Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520400, here are decompositions:

3 + 33520397 = 33520400
31 + 33520369 = 33520400
37 + 33520363 = 33520400
79 + 33520321 = 33520400
97 + 33520303 = 33520400
127 + 33520273 = 33520400
181 + 33520219 = 33520400
271 + 33520129 = 33520400

Showing the first eight; more decompositions exist.
