Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487180, here are decompositions:

17 + 33487163 = 33487180
29 + 33487151 = 33487180
59 + 33487121 = 33487180
131 + 33487049 = 33487180
149 + 33487031 = 33487180
227 + 33486953 = 33487180
239 + 33486941 = 33487180
263 + 33486917 = 33487180

Showing the first eight; more decompositions exist.
