Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486920, here are decompositions:

3 + 33486917 = 33486920
73 + 33486847 = 33486920
79 + 33486841 = 33486920
151 + 33486769 = 33486920
157 + 33486763 = 33486920
223 + 33486697 = 33486920
373 + 33486547 = 33486920
601 + 33486319 = 33486920

Showing the first eight; more decompositions exist.
