Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487168, here are decompositions:

5 + 33487163 = 33487168
17 + 33487151 = 33487168
47 + 33487121 = 33487168
107 + 33487061 = 33487168
137 + 33487031 = 33487168
227 + 33486941 = 33487168
251 + 33486917 = 33487168
311 + 33486857 = 33487168

Showing the first eight; more decompositions exist.
