Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483458, here are decompositions:

5 + 31483453 = 31483458
11 + 31483447 = 31483458
29 + 31483429 = 31483458
67 + 31483391 = 31483458
89 + 31483369 = 31483458
107 + 31483351 = 31483458
131 + 31483327 = 31483458
151 + 31483307 = 31483458

Showing the first eight; more decompositions exist.
