Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483284, here are decompositions:

23 + 31483261 = 31483284
47 + 31483237 = 31483284
67 + 31483217 = 31483284
71 + 31483213 = 31483284
167 + 31483117 = 31483284
191 + 31483093 = 31483284
197 + 31483087 = 31483284
223 + 31483061 = 31483284

Showing the first eight; more decompositions exist.
