Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545172, here are decompositions:

5 + 33545167 = 33545172
53 + 33545119 = 33545172
61 + 33545111 = 33545172
71 + 33545101 = 33545172
151 + 33545021 = 33545172
173 + 33544999 = 33545172
179 + 33544993 = 33545172
223 + 33544949 = 33545172

Showing the first eight; more decompositions exist.
