Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578528, here are decompositions:

19 + 33578509 = 33578528
31 + 33578497 = 33578528
79 + 33578449 = 33578528
229 + 33578299 = 33578528
241 + 33578287 = 33578528
331 + 33578197 = 33578528
337 + 33578191 = 33578528
397 + 33578131 = 33578528

Showing the first eight; more decompositions exist.
