Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554218, here are decompositions:

17 + 33554201 = 33554218
59 + 33554159 = 33554218
167 + 33554051 = 33554218
197 + 33554021 = 33554218
227 + 33553991 = 33554218
251 + 33553967 = 33554218
317 + 33553901 = 33554218
419 + 33553799 = 33554218

Showing the first eight; more decompositions exist.
