Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467008, here are decompositions:

19 + 31466989 = 31467008
31 + 31466977 = 31467008
109 + 31466899 = 31467008
151 + 31466857 = 31467008
277 + 31466731 = 31467008
337 + 31466671 = 31467008
379 + 31466629 = 31467008
421 + 31466587 = 31467008

Showing the first eight; more decompositions exist.
