Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483398, here are decompositions:

7 + 31483391 = 31483398
29 + 31483369 = 31483398
47 + 31483351 = 31483398
71 + 31483327 = 31483398
137 + 31483261 = 31483398
181 + 31483217 = 31483398
229 + 31483169 = 31483398
281 + 31483117 = 31483398

Showing the first eight; more decompositions exist.
