Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533366, here are decompositions:

23 + 31533343 = 31533366
97 + 31533269 = 31533366
107 + 31533259 = 31533366
157 + 31533209 = 31533366
199 + 31533167 = 31533366
223 + 31533143 = 31533366
233 + 31533133 = 31533366
239 + 31533127 = 31533366

Showing the first eight; more decompositions exist.
