Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545378, here are decompositions:

7 + 33545371 = 33545378
67 + 33545311 = 33545378
127 + 33545251 = 33545378
151 + 33545227 = 33545378
211 + 33545167 = 33545378
277 + 33545101 = 33545378
379 + 33544999 = 33545378
439 + 33544939 = 33545378

Showing the first eight; more decompositions exist.
