Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515728, here are decompositions:

17 + 33515711 = 33515728
149 + 33515579 = 33515728
179 + 33515549 = 33515728
227 + 33515501 = 33515728
359 + 33515369 = 33515728
461 + 33515267 = 33515728
569 + 33515159 = 33515728
599 + 33515129 = 33515728

Showing the first eight; more decompositions exist.
