Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533174, here are decompositions:

7 + 31533167 = 31533174
31 + 31533143 = 31533174
41 + 31533133 = 31533174
47 + 31533127 = 31533174
73 + 31533101 = 31533174
83 + 31533091 = 31533174
173 + 31533001 = 31533174
193 + 31532981 = 31533174

Showing the first eight; more decompositions exist.
