Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578784, here are decompositions:

11 + 33578773 = 33578784
17 + 33578767 = 33578784
23 + 33578761 = 33578784
37 + 33578747 = 33578784
97 + 33578687 = 33578784
101 + 33578683 = 33578784
167 + 33578617 = 33578784
227 + 33578557 = 33578784

Showing the first eight; more decompositions exist.
