Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524152, here are decompositions:

19 + 31524133 = 31524152
61 + 31524091 = 31524152
103 + 31524049 = 31524152
109 + 31524043 = 31524152
139 + 31524013 = 31524152
199 + 31523953 = 31524152
211 + 31523941 = 31524152
271 + 31523881 = 31524152

Showing the first eight; more decompositions exist.
