Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578320, here are decompositions:

29 + 33578291 = 33578320
47 + 33578273 = 33578320
53 + 33578267 = 33578320
59 + 33578261 = 33578320
101 + 33578219 = 33578320
173 + 33578147 = 33578320
233 + 33578087 = 33578320
317 + 33578003 = 33578320

Showing the first eight; more decompositions exist.
