Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533298, here are decompositions:

29 + 31533269 = 31533298
89 + 31533209 = 31533298
107 + 31533191 = 31533298
131 + 31533167 = 31533298
149 + 31533149 = 31533298
179 + 31533119 = 31533298
197 + 31533101 = 31533298
317 + 31532981 = 31533298

Showing the first eight; more decompositions exist.
