Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554872, here are decompositions:

5 + 33554867 = 33554872
23 + 33554849 = 33554872
41 + 33554831 = 33554872
83 + 33554789 = 33554872
101 + 33554771 = 33554872
173 + 33554699 = 33554872
179 + 33554693 = 33554872
233 + 33554639 = 33554872

Showing the first eight; more decompositions exist.
