Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515388, here are decompositions:

19 + 33515369 = 33515388
29 + 33515359 = 33515388
31 + 33515357 = 33515388
47 + 33515341 = 33515388
89 + 33515299 = 33515388
131 + 33515257 = 33515388
157 + 33515231 = 33515388
229 + 33515159 = 33515388

Showing the first eight; more decompositions exist.
