Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578720, here are decompositions:

13 + 33578707 = 33578720
37 + 33578683 = 33578720
61 + 33578659 = 33578720
79 + 33578641 = 33578720
103 + 33578617 = 33578720
151 + 33578569 = 33578720
163 + 33578557 = 33578720
211 + 33578509 = 33578720

Showing the first eight; more decompositions exist.
