Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515620, here are decompositions:

3 + 33515617 = 33515620
11 + 33515609 = 33515620
41 + 33515579 = 33515620
53 + 33515567 = 33515620
71 + 33515549 = 33515620
101 + 33515519 = 33515620
251 + 33515369 = 33515620
263 + 33515357 = 33515620

Showing the first eight; more decompositions exist.
