Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515872, here are decompositions:

11 + 33515861 = 33515872
23 + 33515849 = 33515872
41 + 33515831 = 33515872
59 + 33515813 = 33515872
101 + 33515771 = 33515872
113 + 33515759 = 33515872
179 + 33515693 = 33515872
239 + 33515633 = 33515872

Showing the first eight; more decompositions exist.
