Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545380, here are decompositions:

3 + 33545377 = 33545380
47 + 33545333 = 33545380
53 + 33545327 = 33545380
59 + 33545321 = 33545380
173 + 33545207 = 33545380
191 + 33545189 = 33545380
233 + 33545147 = 33545380
269 + 33545111 = 33545380

Showing the first eight; more decompositions exist.
