Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466304, here are decompositions:

13 + 31466291 = 31466304
17 + 31466287 = 31466304
41 + 31466263 = 31466304
47 + 31466257 = 31466304
53 + 31466251 = 31466304
71 + 31466233 = 31466304
83 + 31466221 = 31466304
97 + 31466207 = 31466304

Showing the first eight; more decompositions exist.
