Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578878, here are decompositions:

17 + 33578861 = 33578878
71 + 33578807 = 33578878
131 + 33578747 = 33578878
191 + 33578687 = 33578878
227 + 33578651 = 33578878
401 + 33578477 = 33578878
449 + 33578429 = 33578878
467 + 33578411 = 33578878

Showing the first eight; more decompositions exist.
