Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483164, here are decompositions:

47 + 31483117 = 31483164
67 + 31483097 = 31483164
71 + 31483093 = 31483164
103 + 31483061 = 31483164
113 + 31483051 = 31483164
173 + 31482991 = 31483164
191 + 31482973 = 31483164
257 + 31482907 = 31483164

Showing the first eight; more decompositions exist.
