Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545428, here are decompositions:

5 + 33545423 = 33545428
47 + 33545381 = 33545428
101 + 33545327 = 33545428
107 + 33545321 = 33545428
239 + 33545189 = 33545428
251 + 33545177 = 33545428
281 + 33545147 = 33545428
317 + 33545111 = 33545428

Showing the first eight; more decompositions exist.
