Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578478, here are decompositions:

5 + 33578473 = 33578478
29 + 33578449 = 33578478
41 + 33578437 = 33578478
67 + 33578411 = 33578478
179 + 33578299 = 33578478
191 + 33578287 = 33578478
211 + 33578267 = 33578478
281 + 33578197 = 33578478

Showing the first eight; more decompositions exist.
