Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486640, here are decompositions:

17 + 33486623 = 33486640
29 + 33486611 = 33486640
53 + 33486587 = 33486640
59 + 33486581 = 33486640
167 + 33486473 = 33486640
251 + 33486389 = 33486640
269 + 33486371 = 33486640
359 + 33486281 = 33486640

Showing the first eight; more decompositions exist.
