Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533222, here are decompositions:

13 + 31533209 = 31533222
31 + 31533191 = 31533222
73 + 31533149 = 31533222
79 + 31533143 = 31533222
89 + 31533133 = 31533222
103 + 31533119 = 31533222
131 + 31533091 = 31533222
223 + 31532999 = 31533222

Showing the first eight; more decompositions exist.
