Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533104, here are decompositions:

3 + 31533101 = 31533104
7 + 31533097 = 31533104
13 + 31533091 = 31533104
103 + 31533001 = 31533104
181 + 31532923 = 31533104
223 + 31532881 = 31533104
241 + 31532863 = 31533104
271 + 31532833 = 31533104

Showing the first eight; more decompositions exist.
