Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554320, here are decompositions:

3 + 33554317 = 33554320
29 + 33554291 = 33554320
47 + 33554273 = 33554320
53 + 33554267 = 33554320
71 + 33554249 = 33554320
197 + 33554123 = 33554320
227 + 33554093 = 33554320
269 + 33554051 = 33554320

Showing the first eight; more decompositions exist.
