Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512428, here are decompositions:

17 + 33512411 = 33512428
149 + 33512279 = 33512428
197 + 33512231 = 33512428
239 + 33512189 = 33512428
317 + 33512111 = 33512428
359 + 33512069 = 33512428
419 + 33512009 = 33512428
449 + 33511979 = 33512428

Showing the first eight; more decompositions exist.
