Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483470, here are decompositions:

13 + 31483457 = 31483470
17 + 31483453 = 31483470
23 + 31483447 = 31483470
37 + 31483433 = 31483470
41 + 31483429 = 31483470
79 + 31483391 = 31483470
101 + 31483369 = 31483470
157 + 31483313 = 31483470

Showing the first eight; more decompositions exist.
