Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466320, here are decompositions:

29 + 31466291 = 31466320
71 + 31466249 = 31466320
113 + 31466207 = 31466320
257 + 31466063 = 31466320
269 + 31466051 = 31466320
317 + 31466003 = 31466320
491 + 31465829 = 31466320
563 + 31465757 = 31466320

Showing the first eight; more decompositions exist.
