Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466502, here are decompositions:

101 + 31466401 = 31466502
113 + 31466389 = 31466502
173 + 31466329 = 31466502
211 + 31466291 = 31466502
239 + 31466263 = 31466502
251 + 31466251 = 31466502
269 + 31466233 = 31466502
281 + 31466221 = 31466502

Showing the first eight; more decompositions exist.
