Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475872, here are decompositions:

5 + 33475867 = 33475872
13 + 33475859 = 33475872
29 + 33475843 = 33475872
83 + 33475789 = 33475872
139 + 33475733 = 33475872
149 + 33475723 = 33475872
163 + 33475709 = 33475872
239 + 33475633 = 33475872

Showing the first eight; more decompositions exist.
