Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483404, here are decompositions:

13 + 31483391 = 31483404
53 + 31483351 = 31483404
97 + 31483307 = 31483404
167 + 31483237 = 31483404
191 + 31483213 = 31483404
241 + 31483163 = 31483404
307 + 31483097 = 31483404
311 + 31483093 = 31483404

Showing the first eight; more decompositions exist.
