Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486990, here are decompositions:

37 + 33486953 = 33486990
73 + 33486917 = 33486990
127 + 33486863 = 33486990
149 + 33486841 = 33486990
157 + 33486833 = 33486990
191 + 33486799 = 33486990
223 + 33486767 = 33486990
227 + 33486763 = 33486990

Showing the first eight; more decompositions exist.
