Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485180, here are decompositions:

13 + 33485167 = 33485180
31 + 33485149 = 33485180
37 + 33485143 = 33485180
61 + 33485119 = 33485180
67 + 33485113 = 33485180
97 + 33485083 = 33485180
109 + 33485071 = 33485180
181 + 33484999 = 33485180

Showing the first eight; more decompositions exist.
