Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466404, here are decompositions:

3 + 31466401 = 31466404
17 + 31466387 = 31466404
23 + 31466381 = 31466404
113 + 31466291 = 31466404
197 + 31466207 = 31466404
353 + 31466051 = 31466404
401 + 31466003 = 31466404
647 + 31465757 = 31466404

Showing the first eight; more decompositions exist.
