Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466310, here are decompositions:

19 + 31466291 = 31466310
23 + 31466287 = 31466310
47 + 31466263 = 31466310
53 + 31466257 = 31466310
59 + 31466251 = 31466310
61 + 31466249 = 31466310
89 + 31466221 = 31466310
103 + 31466207 = 31466310

Showing the first eight; more decompositions exist.
