Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533162, here are decompositions:

13 + 31533149 = 31533162
19 + 31533143 = 31533162
29 + 31533133 = 31533162
43 + 31533119 = 31533162
61 + 31533101 = 31533162
71 + 31533091 = 31533162
149 + 31533013 = 31533162
163 + 31532999 = 31533162

Showing the first eight; more decompositions exist.
