Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515842, here are decompositions:

5 + 33515837 = 33515842
11 + 33515831 = 33515842
29 + 33515813 = 33515842
71 + 33515771 = 33515842
83 + 33515759 = 33515842
131 + 33515711 = 33515842
149 + 33515693 = 33515842
233 + 33515609 = 33515842

Showing the first eight; more decompositions exist.
