Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542378, here are decompositions:

19 + 33542359 = 33542378
127 + 33542251 = 33542378
151 + 33542227 = 33542378
211 + 33542167 = 33542378
241 + 33542137 = 33542378
277 + 33542101 = 33542378
421 + 33541957 = 33542378
439 + 33541939 = 33542378

Showing the first eight; more decompositions exist.
