Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485096, here are decompositions:

17 + 31485079 = 31485096
29 + 31485067 = 31485096
37 + 31485059 = 31485096
47 + 31485049 = 31485096
73 + 31485023 = 31485096
79 + 31485017 = 31485096
103 + 31484993 = 31485096
107 + 31484989 = 31485096

Showing the first eight; more decompositions exist.
