Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524164, here are decompositions:

3 + 31524161 = 31524164
31 + 31524133 = 31524164
73 + 31524091 = 31524164
151 + 31524013 = 31524164
211 + 31523953 = 31524164
223 + 31523941 = 31524164
283 + 31523881 = 31524164
313 + 31523851 = 31524164

Showing the first eight; more decompositions exist.
