Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578840, here are decompositions:

67 + 33578773 = 33578840
73 + 33578767 = 33578840
79 + 33578761 = 33578840
157 + 33578683 = 33578840
181 + 33578659 = 33578840
199 + 33578641 = 33578840
223 + 33578617 = 33578840
241 + 33578599 = 33578840

Showing the first eight; more decompositions exist.
