Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33600028, here are decompositions:

5 + 33600023 = 33600028
47 + 33599981 = 33600028
149 + 33599879 = 33600028
167 + 33599861 = 33600028
227 + 33599801 = 33600028
239 + 33599789 = 33600028
311 + 33599717 = 33600028
359 + 33599669 = 33600028

Showing the first eight; more decompositions exist.
