Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466612, here are decompositions:

109 + 31466503 = 31466612
211 + 31466401 = 31466612
223 + 31466389 = 31466612
271 + 31466341 = 31466612
283 + 31466329 = 31466612
349 + 31466263 = 31466612
379 + 31466233 = 31466612
439 + 31466173 = 31466612

Showing the first eight; more decompositions exist.
