Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512218, here are decompositions:

11 + 33512207 = 33512218
29 + 33512189 = 33512218
107 + 33512111 = 33512218
149 + 33512069 = 33512218
239 + 33511979 = 33512218
251 + 33511967 = 33512218
269 + 33511949 = 33512218
281 + 33511937 = 33512218

Showing the first eight; more decompositions exist.
