Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543378, here are decompositions:

5 + 33543373 = 33543378
19 + 33543359 = 33543378
41 + 33543337 = 33543378
47 + 33543331 = 33543378
139 + 33543239 = 33543378
179 + 33543199 = 33543378
191 + 33543187 = 33543378
229 + 33543149 = 33543378

Showing the first eight; more decompositions exist.
