Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487000, here are decompositions:

3 + 33486997 = 33487000
47 + 33486953 = 33487000
59 + 33486941 = 33487000
83 + 33486917 = 33487000
137 + 33486863 = 33487000
167 + 33486833 = 33487000
233 + 33486767 = 33487000
251 + 33486749 = 33487000

Showing the first eight; more decompositions exist.
