Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578864, here are decompositions:

3 + 33578861 = 33578864
97 + 33578767 = 33578864
103 + 33578761 = 33578864
157 + 33578707 = 33578864
181 + 33578683 = 33578864
223 + 33578641 = 33578864
307 + 33578557 = 33578864
331 + 33578533 = 33578864

Showing the first eight; more decompositions exist.
