Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485220, here are decompositions:

17 + 33485203 = 33485220
37 + 33485183 = 33485220
53 + 33485167 = 33485220
61 + 33485159 = 33485220
71 + 33485149 = 33485220
79 + 33485141 = 33485220
89 + 33485131 = 33485220
101 + 33485119 = 33485220

Showing the first eight; more decompositions exist.
