Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533282, here are decompositions:

13 + 31533269 = 31533282
23 + 31533259 = 31533282
73 + 31533209 = 31533282
139 + 31533143 = 31533282
149 + 31533133 = 31533282
163 + 31533119 = 31533282
181 + 31533101 = 31533282
191 + 31533091 = 31533282

Showing the first eight; more decompositions exist.
