Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520720, here are decompositions:

11 + 33520709 = 33520720
53 + 33520667 = 33520720
71 + 33520649 = 33520720
251 + 33520469 = 33520720
281 + 33520439 = 33520720
347 + 33520373 = 33520720
353 + 33520367 = 33520720
449 + 33520271 = 33520720

Showing the first eight; more decompositions exist.
