Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524912, here are decompositions:

19 + 31524893 = 31524912
73 + 31524839 = 31524912
103 + 31524809 = 31524912
149 + 31524763 = 31524912
191 + 31524721 = 31524912
239 + 31524673 = 31524912
269 + 31524643 = 31524912
271 + 31524641 = 31524912

Showing the first eight; more decompositions exist.
