Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483166, here are decompositions:

3 + 31483163 = 31483166
73 + 31483093 = 31483166
79 + 31483087 = 31483166
97 + 31483069 = 31483166
163 + 31483003 = 31483166
193 + 31482973 = 31483166
277 + 31482889 = 31483166
307 + 31482859 = 31483166

Showing the first eight; more decompositions exist.
