Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554172, here are decompositions:

5 + 33554167 = 33554172
13 + 33554159 = 33554172
79 + 33554093 = 33554172
89 + 33554083 = 33554172
151 + 33554021 = 33554172
163 + 33554009 = 33554172
173 + 33553999 = 33554172
181 + 33553991 = 33554172

Showing the first eight; more decompositions exist.
