Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578688, here are decompositions:

5 + 33578683 = 33578688
29 + 33578659 = 33578688
37 + 33578651 = 33578688
47 + 33578641 = 33578688
71 + 33578617 = 33578688
89 + 33578599 = 33578688
131 + 33578557 = 33578688
179 + 33578509 = 33578688

Showing the first eight; more decompositions exist.
