Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545178, here are decompositions:

5 + 33545173 = 33545178
11 + 33545167 = 33545178
31 + 33545147 = 33545178
59 + 33545119 = 33545178
67 + 33545111 = 33545178
151 + 33545027 = 33545178
157 + 33545021 = 33545178
179 + 33544999 = 33545178

Showing the first eight; more decompositions exist.
