Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487216, here are decompositions:

23 + 33487193 = 33487216
29 + 33487187 = 33487216
53 + 33487163 = 33487216
167 + 33487049 = 33487216
263 + 33486953 = 33487216
353 + 33486863 = 33487216
359 + 33486857 = 33487216
383 + 33486833 = 33487216

Showing the first eight; more decompositions exist.
