Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525168, here are decompositions:

5 + 31525163 = 31525168
41 + 31525127 = 31525168
47 + 31525121 = 31525168
131 + 31525037 = 31525168
137 + 31525031 = 31525168
179 + 31524989 = 31525168
359 + 31524809 = 31525168
401 + 31524767 = 31525168

Showing the first eight; more decompositions exist.
