Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578900, here are decompositions:

13 + 33578887 = 33578900
37 + 33578863 = 33578900
127 + 33578773 = 33578900
139 + 33578761 = 33578900
151 + 33578749 = 33578900
193 + 33578707 = 33578900
241 + 33578659 = 33578900
283 + 33578617 = 33578900

Showing the first eight; more decompositions exist.
