Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578820, here are decompositions:

13 + 33578807 = 33578820
47 + 33578773 = 33578820
53 + 33578767 = 33578820
59 + 33578761 = 33578820
71 + 33578749 = 33578820
73 + 33578747 = 33578820
113 + 33578707 = 33578820
127 + 33578693 = 33578820

Showing the first eight; more decompositions exist.
