Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533102, here are decompositions:

5 + 31533097 = 31533102
11 + 31533091 = 31533102
89 + 31533013 = 31533102
101 + 31533001 = 31533102
103 + 31532999 = 31533102
131 + 31532971 = 31533102
163 + 31532939 = 31533102
179 + 31532923 = 31533102

Showing the first eight; more decompositions exist.
