Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578378, here are decompositions:

79 + 33578299 = 33578378
109 + 33578269 = 33578378
181 + 33578197 = 33578378
271 + 33578107 = 33578378
367 + 33578011 = 33578378
439 + 33577939 = 33578378
487 + 33577891 = 33578378
661 + 33577717 = 33578378

Showing the first eight; more decompositions exist.
