Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520660, here are decompositions:

11 + 33520649 = 33520660
83 + 33520577 = 33520660
191 + 33520469 = 33520660
263 + 33520397 = 33520660
293 + 33520367 = 33520660
389 + 33520271 = 33520660
419 + 33520241 = 33520660
479 + 33520181 = 33520660

Showing the first eight; more decompositions exist.
