Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578672, here are decompositions:

13 + 33578659 = 33578672
31 + 33578641 = 33578672
73 + 33578599 = 33578672
103 + 33578569 = 33578672
139 + 33578533 = 33578672
163 + 33578509 = 33578672
199 + 33578473 = 33578672
223 + 33578449 = 33578672

Showing the first eight; more decompositions exist.
