Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466472, here are decompositions:

71 + 31466401 = 31466472
83 + 31466389 = 31466472
131 + 31466341 = 31466472
181 + 31466291 = 31466472
223 + 31466249 = 31466472
239 + 31466233 = 31466472
251 + 31466221 = 31466472
353 + 31466119 = 31466472

Showing the first eight; more decompositions exist.
