Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533198, here are decompositions:

7 + 31533191 = 31533198
31 + 31533167 = 31533198
71 + 31533127 = 31533198
79 + 31533119 = 31533198
97 + 31533101 = 31533198
101 + 31533097 = 31533198
107 + 31533091 = 31533198
197 + 31533001 = 31533198

Showing the first eight; more decompositions exist.
