Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543888, here are decompositions:

11 + 33543877 = 33543888
31 + 33543857 = 33543888
47 + 33543841 = 33543888
97 + 33543791 = 33543888
127 + 33543761 = 33543888
179 + 33543709 = 33543888
199 + 33543689 = 33543888
227 + 33543661 = 33543888

Showing the first eight; more decompositions exist.
