Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485196, here are decompositions:

3 + 31485193 = 31485196
5 + 31485191 = 31485196
89 + 31485107 = 31485196
137 + 31485059 = 31485196
173 + 31485023 = 31485196
179 + 31485017 = 31485196
293 + 31484903 = 31485196
359 + 31484837 = 31485196

Showing the first eight; more decompositions exist.
