Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525008, here are decompositions:

17 + 31524991 = 31525008
19 + 31524989 = 31525008
41 + 31524967 = 31525008
71 + 31524937 = 31525008
199 + 31524809 = 31525008
211 + 31524797 = 31525008
241 + 31524767 = 31525008
331 + 31524677 = 31525008

Showing the first eight; more decompositions exist.
