Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486740, here are decompositions:

37 + 33486703 = 33486740
43 + 33486697 = 33486740
163 + 33486577 = 33486740
193 + 33486547 = 33486740
271 + 33486469 = 33486740
337 + 33486403 = 33486740
349 + 33486391 = 33486740
379 + 33486361 = 33486740

Showing the first eight; more decompositions exist.
