Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466672, here are decompositions:

43 + 31466629 = 31466672
109 + 31466563 = 31466672
271 + 31466401 = 31466672
283 + 31466389 = 31466672
331 + 31466341 = 31466672
409 + 31466263 = 31466672
421 + 31466251 = 31466672
439 + 31466233 = 31466672

Showing the first eight; more decompositions exist.
