Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485312, here are decompositions:

13 + 33485299 = 33485312
31 + 33485281 = 33485312
43 + 33485269 = 33485312
61 + 33485251 = 33485312
109 + 33485203 = 33485312
163 + 33485149 = 33485312
181 + 33485131 = 33485312
193 + 33485119 = 33485312

Showing the first eight; more decompositions exist.
