Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484166, here are decompositions:

5 + 31484161 = 31484166
23 + 31484143 = 31484166
37 + 31484129 = 31484166
73 + 31484093 = 31484166
97 + 31484069 = 31484166
107 + 31484059 = 31484166
239 + 31483927 = 31484166
277 + 31483889 = 31484166

Showing the first eight; more decompositions exist.
