Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515868, here are decompositions:

5 + 33515863 = 33515868
7 + 33515861 = 33515868
19 + 33515849 = 33515868
31 + 33515837 = 33515868
37 + 33515831 = 33515868
97 + 33515771 = 33515868
109 + 33515759 = 33515868
149 + 33515719 = 33515868

Showing the first eight; more decompositions exist.
