Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538272, here are decompositions:

13 + 33538259 = 33538272
41 + 33538231 = 33538272
113 + 33538159 = 33538272
139 + 33538133 = 33538272
181 + 33538091 = 33538272
191 + 33538081 = 33538272
223 + 33538049 = 33538272
263 + 33538009 = 33538272

Showing the first eight; more decompositions exist.
