Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500096, here are decompositions:

13 + 31500083 = 31500096
73 + 31500023 = 31500096
79 + 31500017 = 31500096
107 + 31499989 = 31500096
157 + 31499939 = 31500096
163 + 31499933 = 31500096
197 + 31499899 = 31500096
233 + 31499863 = 31500096

Showing the first eight; more decompositions exist.
