Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524810, here are decompositions:

13 + 31524797 = 31524810
17 + 31524793 = 31524810
19 + 31524791 = 31524810
43 + 31524767 = 31524810
47 + 31524763 = 31524810
89 + 31524721 = 31524810
137 + 31524673 = 31524810
167 + 31524643 = 31524810

Showing the first eight; more decompositions exist.
