Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487090, here are decompositions:

29 + 33487061 = 33487090
41 + 33487049 = 33487090
59 + 33487031 = 33487090
137 + 33486953 = 33487090
149 + 33486941 = 33487090
173 + 33486917 = 33487090
227 + 33486863 = 33487090
233 + 33486857 = 33487090

Showing the first eight; more decompositions exist.
