Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466454, here are decompositions:

53 + 31466401 = 31466454
67 + 31466387 = 31466454
73 + 31466381 = 31466454
113 + 31466341 = 31466454
127 + 31466327 = 31466454
163 + 31466291 = 31466454
167 + 31466287 = 31466454
191 + 31466263 = 31466454

Showing the first eight; more decompositions exist.
