Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524916, here are decompositions:

23 + 31524893 = 31524916
53 + 31524863 = 31524916
107 + 31524809 = 31524916
149 + 31524767 = 31524916
239 + 31524677 = 31524916
347 + 31524569 = 31524916
383 + 31524533 = 31524916
659 + 31524257 = 31524916

Showing the first eight; more decompositions exist.
