Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466708, here are decompositions:

19 + 31466689 = 31466708
37 + 31466671 = 31466708
79 + 31466629 = 31466708
307 + 31466401 = 31466708
367 + 31466341 = 31466708
379 + 31466329 = 31466708
421 + 31466287 = 31466708
457 + 31466251 = 31466708

Showing the first eight; more decompositions exist.
