Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489128, here are decompositions:

19 + 33489109 = 33489128
31 + 33489097 = 33489128
151 + 33488977 = 33489128
181 + 33488947 = 33489128
349 + 33488779 = 33489128
571 + 33488557 = 33489128
619 + 33488509 = 33489128
661 + 33488467 = 33489128

Showing the first eight; more decompositions exist.
