Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479920, here are decompositions:

11 + 33479909 = 33479920
41 + 33479879 = 33479920
59 + 33479861 = 33479920
101 + 33479819 = 33479920
107 + 33479813 = 33479920
113 + 33479807 = 33479920
179 + 33479741 = 33479920
233 + 33479687 = 33479920

Showing the first eight; more decompositions exist.
