Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545180, here are decompositions:

3 + 33545177 = 33545180
7 + 33545173 = 33545180
13 + 33545167 = 33545180
61 + 33545119 = 33545180
79 + 33545101 = 33545180
181 + 33544999 = 33545180
241 + 33544939 = 33545180
283 + 33544897 = 33545180

Showing the first eight; more decompositions exist.
