Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524960, here are decompositions:

23 + 31524937 = 31524960
67 + 31524893 = 31524960
97 + 31524863 = 31524960
151 + 31524809 = 31524960
163 + 31524797 = 31524960
167 + 31524793 = 31524960
193 + 31524767 = 31524960
197 + 31524763 = 31524960

Showing the first eight; more decompositions exist.
