Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499920, here are decompositions:

11 + 33499909 = 33499920
17 + 33499903 = 33499920
23 + 33499897 = 33499920
31 + 33499889 = 33499920
37 + 33499883 = 33499920
73 + 33499847 = 33499920
79 + 33499841 = 33499920
107 + 33499813 = 33499920

Showing the first eight; more decompositions exist.
