Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545458, here are decompositions:

29 + 33545429 = 33545458
131 + 33545327 = 33545458
137 + 33545321 = 33545458
251 + 33545207 = 33545458
269 + 33545189 = 33545458
281 + 33545177 = 33545458
311 + 33545147 = 33545458
347 + 33545111 = 33545458

Showing the first eight; more decompositions exist.
