Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545280, here are decompositions:

29 + 33545251 = 33545280
53 + 33545227 = 33545280
73 + 33545207 = 33545280
89 + 33545191 = 33545280
103 + 33545177 = 33545280
107 + 33545173 = 33545280
113 + 33545167 = 33545280
179 + 33545101 = 33545280

Showing the first eight; more decompositions exist.
