Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487288, here are decompositions:

11 + 33487277 = 33487288
17 + 33487271 = 33487288
41 + 33487247 = 33487288
101 + 33487187 = 33487288
137 + 33487151 = 33487288
167 + 33487121 = 33487288
227 + 33487061 = 33487288
239 + 33487049 = 33487288

Showing the first eight; more decompositions exist.
