Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533128, here are decompositions:

107 + 33533021 = 33533128
197 + 33532931 = 33533128
257 + 33532871 = 33533128
311 + 33532817 = 33533128
557 + 33532571 = 33533128
569 + 33532559 = 33533128
647 + 33532481 = 33533128
659 + 33532469 = 33533128

Showing the first eight; more decompositions exist.
