Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512388, here are decompositions:

5 + 33512383 = 33512388
79 + 33512309 = 33512388
89 + 33512299 = 33512388
109 + 33512279 = 33512388
157 + 33512231 = 33512388
167 + 33512221 = 33512388
181 + 33512207 = 33512388
197 + 33512191 = 33512388

Showing the first eight; more decompositions exist.
