Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487120, here are decompositions:

3 + 33487117 = 33487120
59 + 33487061 = 33487120
71 + 33487049 = 33487120
89 + 33487031 = 33487120
167 + 33486953 = 33487120
179 + 33486941 = 33487120
257 + 33486863 = 33487120
263 + 33486857 = 33487120

Showing the first eight; more decompositions exist.
