Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466018, here are decompositions:

19 + 31465999 = 31466018
127 + 31465891 = 31466018
139 + 31465879 = 31466018
229 + 31465789 = 31466018
271 + 31465747 = 31466018
277 + 31465741 = 31466018
307 + 31465711 = 31466018
439 + 31465579 = 31466018

Showing the first eight; more decompositions exist.
