Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549920, here are decompositions:

13 + 33549907 = 33549920
31 + 33549889 = 33549920
163 + 33549757 = 33549920
193 + 33549727 = 33549920
307 + 33549613 = 33549920
367 + 33549553 = 33549920
379 + 33549541 = 33549920
409 + 33549511 = 33549920

Showing the first eight; more decompositions exist.
