Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515788, here are decompositions:

17 + 33515771 = 33515788
29 + 33515759 = 33515788
179 + 33515609 = 33515788
239 + 33515549 = 33515788
269 + 33515519 = 33515788
419 + 33515369 = 33515788
431 + 33515357 = 33515788
521 + 33515267 = 33515788

Showing the first eight; more decompositions exist.
