Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545128, here are decompositions:

17 + 33545111 = 33545128
101 + 33545027 = 33545128
107 + 33545021 = 33545128
131 + 33544997 = 33545128
179 + 33544949 = 33545128
251 + 33544877 = 33545128
257 + 33544871 = 33545128
317 + 33544811 = 33545128

Showing the first eight; more decompositions exist.
