Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533204, here are decompositions:

13 + 31533191 = 31533204
37 + 31533167 = 31533204
61 + 31533143 = 31533204
71 + 31533133 = 31533204
103 + 31533101 = 31533204
107 + 31533097 = 31533204
113 + 31533091 = 31533204
191 + 31533013 = 31533204

Showing the first eight; more decompositions exist.
