Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466326, here are decompositions:

263 + 31466063 = 31466326
347 + 31465979 = 31466326
569 + 31465757 = 31466326
599 + 31465727 = 31466326
653 + 31465673 = 31466326
677 + 31465649 = 31466326
797 + 31465529 = 31466326
1103 + 31465223 = 31466326

Showing the first eight; more decompositions exist.
