Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579920, here are decompositions:

13 + 33579907 = 33579920
67 + 33579853 = 33579920
79 + 33579841 = 33579920
97 + 33579823 = 33579920
103 + 33579817 = 33579920
151 + 33579769 = 33579920
271 + 33579649 = 33579920
277 + 33579643 = 33579920

Showing the first eight; more decompositions exist.
