Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524122, here are decompositions:

31 + 31524091 = 31524122
73 + 31524049 = 31524122
79 + 31524043 = 31524122
109 + 31524013 = 31524122
181 + 31523941 = 31524122
241 + 31523881 = 31524122
271 + 31523851 = 31524122
283 + 31523839 = 31524122

Showing the first eight; more decompositions exist.
