Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478628, here are decompositions:

19 + 33478609 = 33478628
67 + 33478561 = 33478628
97 + 33478531 = 33478628
151 + 33478477 = 33478628
241 + 33478387 = 33478628
397 + 33478231 = 33478628
439 + 33478189 = 33478628
619 + 33478009 = 33478628

Showing the first eight; more decompositions exist.
