Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533306, here are decompositions:

37 + 31533269 = 31533306
47 + 31533259 = 31533306
97 + 31533209 = 31533306
139 + 31533167 = 31533306
157 + 31533149 = 31533306
163 + 31533143 = 31533306
173 + 31533133 = 31533306
179 + 31533127 = 31533306

Showing the first eight; more decompositions exist.
