Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467922, here are decompositions:

11 + 31467911 = 31467922
23 + 31467899 = 31467922
29 + 31467893 = 31467922
113 + 31467809 = 31467922
383 + 31467539 = 31467922
389 + 31467533 = 31467922
419 + 31467503 = 31467922
491 + 31467431 = 31467922

Showing the first eight; more decompositions exist.
