Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621968, here are decompositions:

67 + 33621901 = 33621968
109 + 33621859 = 33621968
181 + 33621787 = 33621968
241 + 33621727 = 33621968
277 + 33621691 = 33621968
307 + 33621661 = 33621968
409 + 33621559 = 33621968
571 + 33621397 = 33621968

Showing the first eight; more decompositions exist.
