Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466460, here are decompositions:

59 + 31466401 = 31466460
71 + 31466389 = 31466460
73 + 31466387 = 31466460
79 + 31466381 = 31466460
131 + 31466329 = 31466460
173 + 31466287 = 31466460
197 + 31466263 = 31466460
211 + 31466249 = 31466460

Showing the first eight; more decompositions exist.
