Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487258, here are decompositions:

11 + 33487247 = 33487258
71 + 33487187 = 33487258
107 + 33487151 = 33487258
137 + 33487121 = 33487258
197 + 33487061 = 33487258
227 + 33487031 = 33487258
317 + 33486941 = 33487258
401 + 33486857 = 33487258

Showing the first eight; more decompositions exist.
