Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466356, here are decompositions:

29 + 31466327 = 31466356
107 + 31466249 = 31466356
149 + 31466207 = 31466356
293 + 31466063 = 31466356
353 + 31466003 = 31466356
599 + 31465757 = 31466356
659 + 31465697 = 31466356
683 + 31465673 = 31466356

Showing the first eight; more decompositions exist.
