Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466360, here are decompositions:

19 + 31466341 = 31466360
31 + 31466329 = 31466360
73 + 31466287 = 31466360
97 + 31466263 = 31466360
103 + 31466257 = 31466360
109 + 31466251 = 31466360
127 + 31466233 = 31466360
139 + 31466221 = 31466360

Showing the first eight; more decompositions exist.
