Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533340, here are decompositions:

71 + 31533269 = 31533340
131 + 31533209 = 31533340
149 + 31533191 = 31533340
173 + 31533167 = 31533340
191 + 31533149 = 31533340
197 + 31533143 = 31533340
239 + 31533101 = 31533340
359 + 31532981 = 31533340

Showing the first eight; more decompositions exist.
