Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486880, here are decompositions:

17 + 33486863 = 33486880
23 + 33486857 = 33486880
47 + 33486833 = 33486880
113 + 33486767 = 33486880
131 + 33486749 = 33486880
149 + 33486731 = 33486880
239 + 33486641 = 33486880
257 + 33486623 = 33486880

Showing the first eight; more decompositions exist.
