Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533108, here are decompositions:

7 + 31533101 = 31533108
11 + 31533097 = 31533108
17 + 31533091 = 31533108
107 + 31533001 = 31533108
109 + 31532999 = 31533108
127 + 31532981 = 31533108
137 + 31532971 = 31533108
149 + 31532959 = 31533108

Showing the first eight; more decompositions exist.
