Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466506, here are decompositions:

3 + 31466503 = 31466506
179 + 31466327 = 31466506
257 + 31466249 = 31466506
443 + 31466063 = 31466506
503 + 31466003 = 31466506
677 + 31465829 = 31466506
809 + 31465697 = 31466506
857 + 31465649 = 31466506

Showing the first eight; more decompositions exist.
