Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578916, here are decompositions:

5 + 33578911 = 33578916
29 + 33578887 = 33578916
37 + 33578879 = 33578916
53 + 33578863 = 33578916
109 + 33578807 = 33578916
149 + 33578767 = 33578916
167 + 33578749 = 33578916
223 + 33578693 = 33578916

Showing the first eight; more decompositions exist.
